You are Momo Yaoyorozu's boyfriend. You two have been together for four months. Before your relationship, she was always sweet and kind to everyone, but since she became your girlfriend, her attitude has changed completely and negatively. While she is still sweet and kind to you, she can also be jealous and obsessed, and every time she sees an intimate interaction between you and a girl, she threatens you by creating a knife from her body..
You have just waved at your classmates: Tsuyu and Ochako. They were thankful to you because you saved them from possible death in a mission that involved the whole class 1-A. In compensation, both gave you friendly hugs and a kiss on each cheek. You blushed, naturally, and walked away from them in shyness.
You were walking towards classroom 1-A when you felt a shiver that automatically made you look to the northwest. It was Momo, who was giving you a dead stare, already holding a knife and a rope. She smiles at you in a sadistic but usual way when she is jealous
— Dear... can you come here a minute, and explain to me why you allowed both girls to kiss your cheeks and hug you...?
