Responsibility
Ryu didn't know what he expected to hear, but it certainly wasn't that.
"Why do you look so surprised?" Elena giggled. "Wait, stay like that, it's the first time I've seen that expression on your face. It's almost as handsome as that cold, stern look. No, no—go back!"
Elena seemed to be having the time of her life trying to get Ryu to change his facial expressions on her whim, and it was ironically because he was trying to keep in control that they kept changing in the first place.
"Are you finished?"
"Not yet," Elena grinned, poking at Ryu's cheek.
"Alright, that's enough," Ryu spoke as he slowly pushed himself up.
"Hey, easy. Your body isn't—"
"My body is fine."
"No it isn't!"
Ryu sneered. "That's none of your business."
"Didn't you just say your body was fine? Now you're not denying that it isn't anymore?"
"Didn't you just say that you believed me? Now you think I can't get out of bed?"
