The novel is in spanish but it's totally understandable using Google's auto translate system.

I'm cringing and laughing at the fact that they used "bro" instead of hyung. Mini spoiler: there's going to be a part where Jaeyoung teases Sangwoo because he said "Hyung... ah ah faster, faster." Lmao that would be so freaking weird if they use bro instead. (⊙…⊙ )
