is in love with someone else at first. The female lead likes the other guy while the male lead suffers. In the end though, she realizes her love for him.
I've seen 9 End 2 Outs which is similar to what I want.
You might check out Autumn Tale. Its got this story line but its complicated because they grew up in same household....I'll leave it at that. Definitely worth the watch. It is a heavy flick though, not a light rom-com.
