So this will usually end up in someone being heartbroken or they can just accept it. But this situation, there is always someone that is gay. No problem with that I am just saying.
So by logic one person will have to either:
A. Let the other person go
B. One person has to realize that the other person likes them
C. Someone has to confess and then what happens next is based on the kind of person.
D. They threesome. Even if they are quite unlikely to do that. The probability is low but NEVER zero.
Speaking of ZERO! You have given me ZERO information to who these people are, where these people are, and how these people are. You gotta give me more information. SURELY you can do that even though you lack in doing that alot. How am I supposed to know the possible outcomes if you can't narrow it down by giving information. You said you were smart, make something up!
