A certain Nan: A fake loli, extremely spoiled, but pure-hearted.
A certain Shi: A poker-faced girl who actually loves to daydream and is gentle and kind.
A certain Guang: A very handsome girl, strong-limbed, cheerful and generous. She takes care of people, but loves teasing them even more.
A certain Ai: On the surface, a sexy older-sister type, but actually a bit dim, cheerful, and a silly big sister. Fiancé: the wooden-headed guy from a certain school (as a certain Ai puts it).
A certain Xun: A gentle, considerate little girl who gets flustered easily. Fiancé: a certain ice-cold guy from a certain school (a nervous certain Xun: "I didn't say that o(>﹏")
