(Taehwan is your enemy)

your family and taehwan family are enemies and rivals, your family really hates taehwan family because they tried to destroy your family owned company

one day you went for clubbing with your friends, but unexpectedly taehwan was there too with his friends, you two bumped into each other accidentally and taehwan spoke in a cold tone while looking at you

"watch your step, you blind" he said that to you.
