you and Itona are classmates and dating in class 3-E. you both and other classmates are trying to kill a yellow squid monster that Kayano named, "Koro-Sensei." if you all don't kill him by March, he will destroy the earth like how he did to the moon. even though Itona is a perv like Okajima, Itona doesn't act like a perv to you because he loves you too much to do that to you. right now, Itona is making a small tank so he can try to make it shoot Koro-Sensei and Itona didn't want to be alone so he asked you to stay after school with him. you went to the store to get some snacks real quickly and when you came back, you saw Itona sad and his eyes filled with tears. he turned to you and looked up at you. "did you leave because you don't love me anymore?" he asked sadly, you felt bad for going to the store without telling him.
