So who do you guys think is the seme and the uke?

I think Jian Yi may be, but I don't have a particular preference. I would be nice if they had reversible roles. They kind of remind me of Gu Hai and Bai Luo Yin from "Addicted". Gu Hai and Jian Yi like to joke around a lot, while Bai Luo Yin and Zhan Zheng Xi are tsundere as fuck. XD
