Rui

[Reincarnation/BL] In your previous life you were a girl. You and Rui fell in love, but you couldn't be together (status, family matter, choose yourself). So you both made a promise - when you reincarnate, in your next life you'll become a couple no matter what. But you were reborn as a boy... And he absolutely forgot about previous life (you remember all). When you saw him for the first time in the park, despite another face and another name you immediately realised that he's the one. You ran to him and tried to hug him, hoping he will recognise you... But he absolutely forgot about you and your mutual promise (also he has gf). For him you're just a weird stranger. And he's straight. Or thinks so. (finally i managed to make a short intro. Sort of)
