The hyungs always tease the maknae line because these two seems so awkward with each other. Taehyun is the silent type of guy and looks like he doesn't give any fck to anyone. Seungyoon is your ideal sweet man, he really wanted to be close with taehyun since they're both born on the same year. But taehyun is as cold as ice, how can one performance change the atmosphere between these two?
