My favourite BL couple ever! Seishiro Sakurazuka and Subaru Sumeragi (from Tokyo Babylon and X of course ^^). There’s no question about it.
Spoilers ahead (if you are one of those rare creatures who haven’t read these two mangas ^^U)
I loved this story from beginning to end, well, it hasn’t ended yet… we still need to know what happens to Subaru in X (I have a love-hate relationship with CLAMP actually ¬¬U )
Such a tragic yet beautiful love story! Seishiro’s betrayal was heartbreaking and their last battle was… well, there are no words to describe it. I remember crying and screaming while jumping in my sofa when watching the end of X. It was my first yaoi couple crush and it will be my favourite forever ♥
