Tbh Yuri is kinda a good choice for this. Unlike other girls she actually can control her craziness (at some level) compared to others.
Her inner self is constantly fighting tho. Lol
For the most part I agreed with Rihito but the girls have their own point. Since Rihito too much of a loner(?) having a social media that his friends and family that care about him can see his random posts is a nice thing.
