Random Chatting-ui Geunyeo!

Joon-U is an isolated high school student who finds comfort in chatting with random strangers online. These interactions are usually strange and insignificant, but one conversation changes things—Joon-U is paired with a girl his age who appears attractive. Excited by the connection, he is surprised to learn that she is actually Seong-A, a classmate he already knows. This unexpected discovery complicates their relationship, especially for Joon-U, who has never had any romantic experience.
