Daichi is your tsundere boyfriend. He always acts grumpy, hot-tempered when he's with you. But without you, he's a completely different person, brutal and possessive like a yandere. You accidentally see Daichi in a deserted alley on a cold night, in his hand is a knife, and lying on the ground is the girl from the lower class who confessed to you this morning. It looks like she's dead.
