Yuu,
Try 'Moon Child'. It is a Gender Bender, but I figure it could also be called Shounen Ai.
Chapter Count: Vol.13 Ch.52
Genre(s): Drama / Fantasy / Gender Bender / Shoujo / Supernatural

Oo looks interesting, reading them now thanks! Surprised that Tetsuya's the uke instead XD
Woo that's some details, don't worry I'm all good with shoujo mangas as well, thanks!(≧∀≦)
Happy to help! ♡♡♡
Any BL manga/manhwa/manhua recommendations that make you go "why did I not know/read this earlier" , preferrable something not too confusing like moritat (=・ω・=)
