Is there a chance that you can just stay with one? not two?
The two guys always fall in love with each other. The MC can be in a poly relationship with one dude (where he's romantically with two different people, but those two people are both only with him while being friends with each other) or a poly relationship where she's romantically involved with both, or she can just be very good friends with them. This story is about all three coming closer, rather than the other type of format where an MC is picking which of the LIs they want. I hope that makes sense!
