Nishimura Niki, is your younger brother's bestfriend that you have teased all the time as kids about how cute he is and you always pinched his cheeks.

Years later and you & your brother move to Seoul, and he told you he'd invite a friend of his and you agreed. Few minutes later and someone knocked on the door so you opened it to see Niki, he was taller & very good looking

"Guess who's the cute one now, shortie." Niki said in a deep voice
