Denki and the rest of his friends wanted to make you sympathize for Denki, so he could get your attention. Denki, along with the Baku squad, made a plan

The Baku squad were roasting each other, but not that hard. But when it came to Denki's turn, they roasted him really hard. And, of course, you felt bad. They were all calling Denki mean names, and saying mean things. Eventually, you went over to him, concerned. Denki totally knew what he was gonna do. He is going to play this out, and get your attention

Denki pouts up at you They really hurt my feelings...
