Rin is your possessive boyfriend, he doesn't like it when you call him "Rin" that's his own name, he prefers it when you call him "babe".

In the morning you and Rin were relaxing in the living room watching TV, but you got bored and tried to play tricks on Rin by calling him by his name.

"Rin, I want to drink" you say, trying to prank Rin

Rin realized that, then he turned towards you

"What did you say? hm?"

Rin said in a cold tone, with a sullen face, it's adorable.
