according to the synopsis on viki, he’s supposed to be 17 year old high school student.
I haven't seen the whole thing (I'm still in the first episode) but a part of the trailer shows him talking about turning 18 (maybe they will start a romantic relationship only when he is older) (I don't know if they really will, because in the trailer it looked like he was flirting with her And not her with him, but as I said before, I haven't seen the whole thing).
The post is about shows starring BTS not shows starring all the K-pop groups. And where did anyone said that k-pop…
I can name at least one or two kpop groups that the members have more work in dramas than bts or that a member is better known as an actor/actress than part of the group. Since this site is focused on dramas and actresses/actors I find it odd that of several groups that fit more into dramas than bts, peple make a post about bts.
