Thoughts on Guardian

I recently finished rewatching a chinese drama called Guardian. I know at the time of its airing, this show was very popular, at least in Asia. But now I don't think there's that many fans now as The Untamed and Word of Honor basically kicked Guardian out of its throne in chinese bl/bromance world.

I can proudly say I love the show, love the characters and love the OST so freaking much.

What do you think about this show?
