Izuki-kun wa Tadasaretai

Izuki-kun has a senpai he's interested in—none other than the strict Disciplinary Committee President, Ririko-senpai! To talk to her, even just a little, Itsuki-kun deliberately tries wearing his uniform improperly and makes various efforts, but Ririko is always one step ahead of him!?
