Okay. So, I just finished watching it. It is definitely NOT a BL. So we can rule that out. There are some very few suggestive subtle bromance moments that almost to me felt like Queerbaiting, at best. Yoon San Ha is funny. I loved him. Kim Kang Min was very good too. Their banter was hilarious. I really enjoyed it. But definitely not BL and not bromance either to be honest.
It has 21 episodes on Viki. Does anyone know where the first season ended?
I wouldn't call it first season, but first part and second part would probably be more appropriate terms to describe it. The first part ended after episode 10. The second part is from episode 11 through 21.
