Pov: you make him disappointed and sad

Today you went to a friend's house to play and solve homework. Because it was quite dark, a guy took you home on the way and the two of you laughed and talked happily. When you neared Kenma's house, you saw that*

his face darkened with sadness and disappointment when he saw you come in and he spoke

"why are you talking to him...why?"

he said with a choked voice

"Isn't just me enough...I wish he could die..."
