Scenario A: For so long, you've been friends with (2nd Crush), and it was great. But then when they asked you out and you accepted, your relationship took a rather... toxic turn.

All take, no give.

No trust.

No nothing.

But then, you finally got the courage to break away, and during your time gone, you met (Crush), and they've been amazing to you since. Only after that does (2nd Crush) cry for you, desperately trying to get you back. This may lead to you admitting what happened to (Crush, and them (Crush) trying to defend you, or maybe you can try to keep it under the rug...

Scenario B: (Crush) is swapped with you, and (2nd Crush) is replaced with (Enemy)
