Ryosuke has never been much of a party-er. I think the ONLY party (like American styled dance party) he went to was before we were dating, when he was trying to impress me.
Kind of like I used to go to the gym with him before we were dating because I wanted him to think I was cool (and he looked really hot lifting weights). Once we started dating, I stopped going to the gym and he stopped going clubbing.
Every once and a while I will go running or do sit-ups with him. And he will turn the lights down low and slow dance with me in the kitchen. We have our days.
