I'm sorry- I don't want to say this, but better tell you the truth here.... read it carefully.
It is impossible! There is nothing about any "MAHOU" (magic). This is natural and you better leave her. You see- you said "there would NO future for between myself and her". See- then, you give her up and see other STRAIGHT girls. Just let her go, and I feel that would NEVER happen. Remember, you can't control people or change people!
I can tell something for you. "DON'T WASTE YOUR OWN TIMES".
Wow.... I think I might misunderstood Japanese. Nuance of Japanese is bit kinda difficult...! I wished I could type in Japanese- but, sorry that my Japanese computer is still packed in storage.
Thanks for agreeing with my comment. I can say that love is no blind- there is NO magic or trick. We will never know what is going on. It's the same thing that money cannot buy any love.
