You are walking towards the Faculty of Psychology building. In order to enter the room....you know well that you have to go through the building of the Faculty of Engineering at Dazai is studying (Dazai is your ex. And yes, you don't want to see his face so much, but God makes fun of you and makes you have to. meet him).....(Even though you don't feel anything for him, seeing him being flirted by girl make you jealous)
