Asa made Jugyou Chu!

Kagami Yuuki, a scholarship student, finds himself in an unexpected situation at his new high-class high school due to a registration mistake stemming from his gender-ambiguous name. Teacher Kakinozaki Ayana mistakenly lists him as a girl, a mistake that cannot be corrected. As a result, Yuuki must reside in the girl's dormitory, with Ayana taking responsibility for the error by becoming his roommate. To avoid discovery by the other girls and the subsequent expulsion from both the school and the dorm, Yuuki is forced to cross-dress outside of his classes. This precarious situation demands that both Yuuki and Ayana maintain the charade, ensuring their secret remains hidden from their peers.
