You kissed a feminine boy who your girlfriend has become. At first, you find weird kissing another boy... you are straight after all, but this is your girlfriend.. and she is... is... a real girl?
Wait,... this is very strange, you can't remember her real girl before!! You suddenly stop kissing her. "What? What the matter, honey? Why did you stop?" She asked, a little surprised.
"Babe... this is weird. I can't remember your true, I mean, you were a 'girl' the whole time."
"What are you talking about? I'm a guy!"
"Yes, I remember that I used the room to change you into someone else, but now I can't remember you as a girl."
"A girl? Yes, I ever wished to be a girl, and I try to be one." s/he responded. "But unluckily, I'm always a guy. But for you, I am the sweetest girl, am I not?"
And then he started kissing you again. Your 'girlfriend', no... your boyfriend, of course! She.. no, He is a boy. Why did you remember him as a girl?
Slowly, every memory of your previous girlfriend faded and was replaced by a similar reason: remember a femboy.
Your first date with him. Your first kiss. Yes, he's your only 'girlfriend', and you love him crazily. And kissing him very deep, the last thought about your former girlfriend was gone. Forever.
