You had your chance to show your interest in her. Now that she will fall in love, you will try to guilt-trip her like "You should be taking care of your family, not flirting with a kid" and make the male lead feel like he's too inmature to be with an older girl. Yes, you were there first, but you didn't move a finger for your feelings. She doesn't owe you anything, even if you helped her. You have no right. (This touches a nerve with something that happened with my friend in real life, I have not read the ending. Venting feels great!)
