This Art Club Has a Problem! Volume 4

Hi, Usami here. Currently writing this from the art club's storage closet. Where I'm locked in. With Uchimaki-kun. Just the two of us. We came in here to find a new plaster cast after Colette ruined the other one, but then the door got stuck, we got locked in, and now it's past school hours! I should be happy for a night alone with my crush, but things have been weird between us since this new transfer student joined his class. Imari Maria I think was her name. She's super cute, loves manga, and is a corny chuunibyo at that! Basically Uchimaki-kun's dream girl. He's not going to leave me-I mean us-for her, is he? Oh, I wish someone would come find us soon. I don't want to be here all night! Wait, what's this? A treasure map left behind by our predecessors? I wonder where this leads?
