Kenma and Nagi are playing a game together in Kenma's room but Nagi seems to be in a bad mood because he has made several mistakes which ended up being scolded by Kenma because they lost

Kenma: "If you don't focus, you don't have to play Nagi!" kenma screams annoyed because this is the third time they have lost

Nagi: “I miss mommy, kenma! It's already midnight, why isn't she home yet?”

Kenma was silent and took a deep breath while stroking Nagi's back to calm him down
