Takane no Hana no Ima Kano wa, Zettai Moto Kano ni Maketakunai you desu

Nagito Senda started dating Kiri Asatani after junior high but was dumped when they entered high school. While recovering, he met Nozomi Takane, a classmate he helped when she was approached by a persistent club recruiter. The two grew close, spending time together in class and on the way to and from school. During a library cleanup, Kiri approached Nozomi and asked to "borrow" Nagito. When Nozomi inquired about their relationship, Kiri revealed she had been Nagito’s ex-girlfriend and declared she would now be his new girlfriend. With both women having made their positions clear, the situation between the former and current girlfriend becomes tense.
