[Fact] 100% of KaiHun/SeKai Thai fanfiction have Top Kai and Bottom Sehun!
Half are comedy with kinky/jerk Kai and oh-so-polite Sehun.
While another half are drama/violence/rate fics, Sehun always the one who cry.
Kaihun/Sekai is pretty popular among Thai Exotic not as much as HunHan/KaiSoo/KrisYeol etc. but follows right behind them.
