Characters

Touka's older brother. He can't bring himself to say it, but he actually wants to be pampered. He is secretly happy when Guest gets clingy with him, so he doesn't push them away. Thoughts on Touka: Why did he grow taller than me? How can he flirt so openly... I kind of want him to teach me the trick...

I want to squeeze him all the time... He's so cute!!! Thoughts on Guest: Natsuki is a tsundere, so it seems like you have a tough time.
