Sanada didn't bother to reply about the endorphins and just looked down at Niou's hand. He was pretty sure that hurt Niou more than it hurt him.

"If you're making your bed bigger and sturdier, I'm guessing it's more than a crush. Why would it be embarrassing?" Sanada asked. Maybe Niou didn't think Tachibana and Akutsu were respectable boyfriends and didn't want people to know they were together because of that. Sanada could potentially see that.
