Chie, Monji's childhood friend, is having troubles with the man she's in love with, as she deeply loves him but he's not really willing to reciprocate: he'll play around but won't get serious, and she breaks down crying because of it while Monji has to comfort her. After an outing with his three male friends, Monji is happy to leave with Chiba (who still seems somewhat disinterested). However, Chiba ends up steering Monji in the direction of a love hotel.
There, Monji is uncomfortable and seems upset, and we learn that he had actually confessed his love to Chiba – but it's a similar situation to Chie, where Chiba doesn't seem like he's serious about wanting a relationship with Monji, but is willing to have sex with him.
