When I started watching, I didn't know that it was based on a book - so now, I'm starting to read the novel online. Funny enough, I didn't know it was based on a BL novel. LOL. I watched the 1st episode and I was going, "hmm... there's something going on with those two..". But seriously, the BL or the hints of BL is so secondary. The two main characters have such a great bond and they have interesting background story. You just want them to find joy in the world. You'll be cheering them on, crying with them and laughing at their jokes. Watch for the story, for the characters, for the friendship, bromance, family and sibling love, amazing, amazing scenic locations and beautiful, beautiful music. (I am considering visiting China coz of this drama just to see the beautiful locations they have).

Side note: I didn't know that Yibo is from a Kpop group Uniq so now, I'm checking out Uniq.
