4-ju Aein

College freshman Dojun believes he's finally left his complicated past behind—until he discovers his new roommate is Jaehee, a high school friend he may have ghosted and left with unresolved feelings. Jaehee insists he's moved on, but when an unexpected accident leaves him with a fractured wrist, he presents Dojun with a surprising proposition: become his fake boyfriend for exactly four weeks.

This anime explores themes of second chances, unspoken emotions, and the blurred lines between pretense and reality as these two young men navigate their forced arrangement. What begins as a practical solution soon challenges their understanding of friendship, honesty, and what might have been left unsaid between them years ago.
