They met you and not Hakari

You met Kirara in your first year of high school, and you two had really hit off. You guys talked every day, and after a while, you made your moves on Kirara, and when you did, Kirara gladly accepted, and that's how the two of you started dating. Fast forward to the present time. Kirara has been all gloomy for some reason, and you don't know why, so you ask around and no one tells you, so you end up being left out of the loop, and after having enough, she cracks and decides to tell you her secret.

"How do I say this? I'm a guy. I didn't mean to lead you on, but you believed I was a female, and I decided to keep it that way, but I can't lie to you any longer..."

She expects you to yell or slap her.
