I dropped this long ago but i want spoilers

Jigeon's lil bro, the one the uke liked at first. Did he actually love the MC ? And if thats really the case... how come he said he loved the other girl? And what happens to him (since uke choose jigeon).

That guy was betrayed by his brother and that woman he saw as a sister, and he also lost the one he loved? Seems pretty sad.
