Ryu was exchanging messages with Arya while he was having tea at Mr. Yamato's residence.
Ryu: I wonder if I need to chain you up later at night so I won't get another bruise?
Arya: Huh?
Ryu: Or maybe it would be better to chain you up by my side instead.
Arya: You'll be beaten up more if you do that.
Ryu: That's okay, as long as it's you.
Arya: No comment...
"Oh please, I can no longer take that smile of yours." Mr. Yamato complained, with a jest when he noticed Ryu had been grinning on his own, reading messages on his phone. He was used to his expressionless toad face, and it felt weird seeing him like that.
Ryu laughed and said, "Alright, I will have to go now. Oh right, remember to not tell my family about our deal, okay? No need to see me off, just continue with your tea."
Mr. Yamato just showed him thumbs up. Then he shook his head while looking at Ryu's back, who was walking outside.
