Himitsu ni Shiro yo!!

Koshika is an ordinary high school student with a lifelong appreciation for all things cute. Beneath his everyday exterior, however, he harbors a deeply personal secret: he enjoys cross-dressing as a girl. He has carefully kept this hidden passion to himself, fearing the judgment of those around him. Unfortunately, his meticulous efforts to maintain his privacy are shattered when his classmate, Oozeki, accidentally stumbles upon him in disguise. Terrified that this unexpected discovery will lead to damaging rumors spreading throughout their school, Koshika is forced into a difficult position. To ensure his secret remains safe and to keep a close watch on the situation, he makes the drastic decision to shadow Oozeki constantly. By following his classmate everywhere he goes, Koshika hopes to monitor him closely enough to prevent any whispers from reaching the rest of the student body. What begins as a desperate attempt at damage control quickly turns into an unavoidable entanglement between the two classmates, leaving Koshika to navigate the stressful balance between protecting his hidden hobby and managing his newfound, self-imposed surveillance duty.
