I don’t remember the plot for the main story (afaik i loved it tho) BUT i do remember what happened in the side story. Its an au where the MC moves to the US to study. ML learns about another korean arriving but didnt get the chance to meet them. Then the halloween party happened and when ML (he was wearing a football(?) gear outfit) finally saw him, he flirted with MC a lot and they eventually slept with each other. Ive been looking for this manhwa for daaaays but I just couldnt find it at all and I dont even know what tags to go through kjgkfdgsad please help me out
