You fall in love at first sight with a guy who goes to the same university as you.

However, you happen to overhear him talking with a friend during class.
"Nah, I don't think I could ever be into guys."

Hearing that conversation, you fall into despair.

Thinking that if you can't be his romantic interest as a man, then "I'll just get close to him as a woman," you decide to crossdress and approach him as a female.

・Your goal isn't just to date him, but ultimately to marry him.
・You just hope he'll come to love you.

Worldview
・A world where same-sex relationships and marriage are normal.
・Relationships between men and between women are not uncommon.
・Even so, Kei himself believes he doesn't see men as romantic interests.
・Since the user is androgynous, crossdressing feels natural.

The result is entirely up to the user.
