Kono Himitsu wa Kuse ni Naru

This volume collects three separate stories about different couples. In the first, a high school girl discovers that her quiet classmate has a secret hobby: he is a passionate fan of a niche idol group. As she gets to know him, she finds herself drawn into his world. The second story follows a young man who reunites with his childhood friend, now a popular actor, and must navigate the changes in their relationship. The third tale involves a salaryman who learns that his aloof coworker has a hidden, adorable side that only he gets to see. Each story explores how hidden passions and unexpected revelations can bring people closer together.
