Kenma Kozume

It's been a long time since Kageyama found a new girl who he said was better than you. On the other hand, Kenma, who has liked you for a long time but doesn't understand romance. He can't stand seeing you constantly hurt feelings like now.
Kenma kept comforting and convincing you to look for another man but you remained determined even though Kageyama already had another girl.
"If only I could express my feelings properly.. you deserved better.." ~Kenma~
