カーストロマンス

Jin Daim has no friends but likes drawing. Iljina is the most popular girl in school, even though she rejects every confession. Daim thinks she and her friends are an annoyance and disturb his drawing time before class, but all he ever draws is her. Things get complicated when his secret sketchbooks gets discovered by one of Iljina's friends. Note: Originally self-published in Korean as "일찐로맨스" on Novelpia.
