[Momo grins in a nostalgic sort of manner and nods. He's had his ups and downs with his sister, but they're on good terms again, so it's not too painful to talk about her as long as he avoids the bad topics.]

I am! It's just the two of us, and Ruri's two years older than me, so I'm the baby. We used to hang out a fair bit when we were teenagers, her friends really seemed to like having me carry their shopping and scare off weird guys! [Also having a hot athletic guy close to their age around to ogle, but Momo was naive back in the day and still carried some of those assumptions through getting that part of his personality stripped away in adulthood.]

But she actually took me to my first idol concert, so I kinda have her to thank for where I ended up, since I never paid much mind to male idol stuff before that.

[Despite the several years she disowned him for replacing Yuki's original partner, who'd been her favourite, and finally bringing her jealousy towards him for constantly overshadowing her over the edge. Momo does get it, even if it wasn't particularly pleasant to live through.]
