your name is kang y/n. ur taehyun's little sister. ur brother is in a boy group called txt. you moved in to their dorm and taehyun is always protecting you. but what taehyun doesnt know, you and beomgyu have been dating for almost 6 months.. the other members knew and always say to tell ur brother but ur not sure when to tell him as he is very protective of you. you and beomgyu always distances yourselfs when ur brother is around but always together when he isnt. one day all of them were in the living room. hueningkai, soobin, and beomgyu played games while taehyun and yeonjun watched. you were at the kitchen by urself, eating snacks in pajamas and messy hair.
