To the non teumes, this is the first web drama of a 6 months old rookie K-pop group called Treasure. Teume is the fandom name of Treasure. The story revolves around how two brothers who are twins, got in to the high school and got closer to the famous boys. Yes this drama has the same cliche BOF plot but you'll definitely enjoy it. Chemistry between who played as main leads is really good. Note that they are not actors and just debuted. Give it a try.
Bonus: They didn't make anyone play the girls role. This is an all boys drama. It has BL vibe more than some actual BL dramas xD
