I now remembered what this reminds me!! It was a movie with Reese witherspoon (I love that lady), Legally blonde was it?
Yes yes!! And she ends up with the other guy in the end and becomes successful lawyer! But in this case his ex in the manga still loves him. Ok I wouldn't call it love though if you truly love someone you don't sacrifice your love so easily. Dark haired dude is better for mc. The glasses dude will probably end up with blonde ex.
That was sooo cute *ugly crying noises*
