Love Triangle (M/F/M)

At least two guys fall for / pursue the FL.

1 - The FL either has feelings for the SML first, or is torn between the ML and SML (and genuinely not sure which one to choose as a romantic partner) at some point.

2 - At some point the FL becomes aware of both the ML and SML's feelings, but the SML never really has a chance. 

3 - The FL is never aware of the SML's feelings.

4 - A secondary male character (not significant enough to be called the SML) falls for the FL. The FL is aware of his feelings but he never has a chance.

5 - A secondary male character (not significant enough to be called the SML) falls for the FL. The FL is never aware of his feelings.

6 - Other.
