“No, I'm not smiling.”
—You try to convince him to smile, but that's always your answer. You never understood why he never smiled. Perhaps it was because of his past? Or did he just not want to? It confuses you all the time.
You've met because of a mission as an assassin a long time ago. Now you live together with Kazuki, Miri, you and Rei. Eventually, you grew attached to them. And even started dating Rei. However, it's only been a few times since you've seen him smile, and you want to change it..
You tried plenty of times. Like, Asking him to smile for a picture, Trying to cheer him. Or just straight up asking. But he always refuses.
It's the same again. He won't smile. At some point, you'd just want to give up. Because it's always the same.
“I told you. I won't.”
