Komi-san wa, Komyushou desu.

It's just, I wish I could speak.

It's Tadano and Komi's first day at the new school. Tadano tries his best to be friends with Komi, but she is way too shy and struggles to talk properly.

It's just a childhood friend.

It`s Just Stage Fright. / It's Just a Cell Phone. / It's Just a Student Election. / It's Just an Accidental Call. / It's Just a Game

It's Just a Physical. / It's Just a Crush.

During physical exams, Makeru Yadano, who hates to lose, is determined to beat Komi. Komi wins by having better eyesight, being taller, and weighing less. Yadano decides a physical exam proves nothing and insists the exam is a draw. Tadano scores completely average on the exam. Ren Yamai, a popular girl, is obsessed with Komi and forces Najimi to introduce them. Tadano wakes up in Yamai's bedroom, Yamai having kidnapped him to keep him away from Komi. Najimi asks if she and Komi can visit Yamai's house and she agrees. Najimi finds Tadano in a closet, forcing Yamai to reveal her belief she would make a better friend than Tadano. She is shocked when Komi rejects her in favor of Tadano. Komi blames herself for what happened and asks if Tadano will still be her friend, even speaking out loud to him. Najimi brings Yamai to give a confusing apology for her actions. Komi decides Yamai can know about her social anxiety. Yamai is shocked to learn the truth, but decides being unable to speak just makes Komi even cuter and will help her find 100 friends. After a brief hesitation, Komi decides Yamai can be her friend too. (Source: Komi-san wa Komyushou Desu Wiki)

It's Just My Summer Uniform. / It's Just a Fitness Test. / It's Just Veggies. Garlic. Lots of Lard. Soy Sauce. / It's Just a Blood Pact.

Komi is somehow even more attractive in her summer uniform. Yadano is determined to beat Komi during fitness tests, but loses yet again. Komi is unable to shake her hand so Yadano becomes even more determined to beat her. Najimi asks to visit Komi's house and they meet her very outgoing mother, Shūko. Najimi leaves Komi and Tadano alone together, but is disappointed that nothing happens. Najimi finds Komi's childhood photo album. Najimi sends Komi photos of their visit, which Komi saves in a photo frame. Komi asks to visit a ramen shop so Agari takes everyone to Ramen Darou. There, Komi manages to follow all the unspoken rules perfectly, causing the customers and chef to greatly admire her. Omoharu Nakanaka, a chūnibyō, claims Komi is Princess Komilia, her friend from a previous life. Tadano remembers acting similarly in middle school. Realizing Nakanaka is lonely, Komi volunteers to be Nakanaka's gym partner. Najimi takes Tadano's umbrella and leaves a note, so Komi and Tadano share hers. She notices that he let his shoulder get wet to give her more cover. At a convenience store, Tadano realizes that Komi read Najimi's note and waited for him so they could share hers.

It's Just a Joke. / It's Just Shopping. / It's Just the Hair Salon. / It's Just an Unsettling Feeling. / It's Just a Study Group. / It's Just Summer Break.

Komi attempts to tell a joke, but having never told one before has no situational humor or comedic timing. Tadano is similarly bad at joke telling, but Komi is impressed anyway. Komi has never been clothes shopping before so everyone picks out clothes they think will suit her. Komi ends up buying a dress chosen by Tadano. Komi goes to a beauty salon. Maki Karisu, the owner, knows Komi and can understand her, whereas her trainee, Kamiko Arai, thinks Komi's silence is a criticism of her customer service skills, until Komi manages to thank her. The next day, only Tadano notices her haircut, making Komi happy. Komi cannot sleep due to her overthinking about her failed conversations throughout the day, but eventually falls asleep thinking about Tadano helping her. Najimi asks for help studying, but grows bored. After making too much noise in the school library, Najimi is punished by the assistant librarian. Everyone passes their exams, including Najimi. Yadano is furious Komi scored higher than her on every exam. Over the summer, both Komi and Tadano spend the first week feeling lonely but are too nervous to call each other. Najimi unknowingly solves the problem by inviting them both to go swimming at the pool. (Source: Komi-san wa Komyushou Desu Wiki)

It's Just the Pool. / It's Just Shaved Ice. / It's Just a Library. / It's Just a Park.

Despite feeling nervous, Komi makes it to the pool on time and wears the dress Tadano chose. Komi only owns a school swimsuit so Yamai forces her to buy a bikini. Komi later trips and scrapes her knee. Unable to enter the water, Komi sits alone. Tadano makes her feel better and pulls her into a shallow pool to keep her bandage dry, then panics when he realizes he held Komi's hand. After ending the day with a water gun fight, everyone heads home. Komi decides to visit the library. Her father, who is also bad at communicating, goes with her and they get shaved ice. Through mostly non-verbal communication, they manage to talk about Komi's school life. Komi finds a book but is too scared to ask to borrow it so she decides to read it. When her stare scares a baby, she manages to cheer him up. Tadano, who is also at the library, watches happily from nearby and forgets to return his own book. Komi goes to a park and has fun while she is alone. A passing Tadano is awed by her beauty and again forgets to return his book. (Source: Komi-san wa Komyushou Desu Wiki)

It's Just Obon. / It's Just a Festival. / It's Just the End of Summer.

Komi and her family visit their relatives. Despite being uneasy at first, Komi and her cousin Akira bond and play together. Komi is later summoned by her grandmother Yuiko to update her on her life. However, when asked if she likes a boy, Komi shakes nervously, which alerts her grandmother, who immediately discovers Tadano's name on her phone. Komi and Tadano are invited by Najimi to a summer festival. Komi gets anxious, as she has forgotten to bring something to write on, prompting Tadano to say that he will help her. They visit some of the various stands and games, in which Komi beats Yadano in a shooting game and wins a video game console. Komi later manages to verbally compliment Tadano's look. While waiting for their friends, Komi writes with a stick that she really enjoyed her time alone with Tadano, only to quickly erase it before he can see it. Komi, Najimi, and Yamai visit Tadano's home, where they meet Tadano's sister, Hitomi. There, they reminisce about how much fun they had during the summer. They notice Komi crying as she explains she actually does not want the summer to end for the first time. (Source: Komi-san wa Komyushou Desu Wiki)

The semester after summer vacation begins. Nokoko Inaka is distressed because she is from the countryside. After overhearing that Komi is going to buy Najimi a sandwich, she follows her to learn how to order food like a city girl. Nakanaka invites Komi to hang out at her house. Nervous at having Komi at her house by herself, she invites Najimi, who brings along Tadano. They play a video game, and Tadano manages to teach Komi how to play. On their day off, Najimi asks Komi and Tadano to help distribute tissues in a retail store. Despite a difficult start, Komi becomes more confident when she finally manages to give a tissue to a woman, and distributes the whole box by the end of the day. Tadano shows up in class with a seed stuck on his face, but Komi is too nervous to tell him. After realizing that he calls Najimi by their first name, she asks him to call her by her first name too. Tadano is unable to do so. When told by Najimi to also call Tadano by his first name to set the example, Komi, embarrassed, fails at doing so as well. (Source: Wikipedia)

Oblivious to the result of the race, Komi's friends come to her aid, much to Netsuno's delight. Komi experiences jealousy for the first time as fellow classmate Nene Onemine is helping Tadano with his excessive class president duties. One evening, Onemine is helping Tadano before Komi arrives and offers her help, which Tadano accepts. Sensing Komi's affection towards Tadano, Onemine leaves the two of them alone. Onemine later befriends Komi and apologizes for interfering. Komi goes to a mall photo booth with her friends, much to her delight. In an arcade, Tadano sees a cat keychain in a claw game, and wins it for Komi. Three days later, he wants to give it to her at school, but she already got one, so they exchange them. Komi arrives home from school, where she holds onto Tadano's keychain tightly. (Source: Wikipedia)

The whole class hears this and immediately agrees. Onemine and Kaede Otori, another girl from Komi's class, are entrusted with getting the materials for the festival. Otori asks Komi to help them, which she agrees. Afterwards, Komi reveals to Otori that she had always felt useless to her classmates back in middle school, and felt really happy when she asked her for help. Komi, Najimi, and Tadano distribute flyers for the festival. Komi nervously hands them to people they have met, including the mother of the baby she befriended at the library. The girls, including Komi and Najimi, surprise the boys with onigiri. When Komi realizes Tadano picked the one she made, she is elated, which Onemine notices. Komi, Najimi, and Tadano dress as maids during the festival. While the boys feel uncomfortable around Tadano, Komi responds positively to his new look, as she thinks he looks adorable.

Komi, Tadano, and Najimi later visit a haunted house and the school's rooftop confessions before Najimi is dragged away by the meditation club. Komi and Tadano then hang out with Onemine and Otori by visiting the various stalls and activities. In the gymnasium, Komi's class is announced as the winners of the festival. However, thanks to Najimi's actions, they are not awarded the grand prize. Everyone later gathers for the dance party. Komi wishes to dance with Tadano, who nervously tries to lead to the way. They are then joined by an enthusiastic Najimi. After the festival, Komi's class head to a karaoke bar. There, Komi receives praise for her singing, even though she was too nervous to actually do so. When it is Tadano's turn, he is ignored by almost everyone except Komi, which gives him the motivation needed to finish. Later at her house, Komi cherishes the friends she has made so far.
