Incredible. When i first saw this title and read the description, i was kind of hesitant but nevertheless i watched it. I dont regret it at all. Its way too underrated, but so worth it. If you like action dramas (especially BLs), watch it. Seriously. It deserves more recognition. The way they didnt know who each other was at the beginning was funny af. They met randomly and one was actually the other ones biggest fan. Adorable. But also the fact that the fan was secretly an assassin just like him. The ending was sad but oh well it is a drama. Just do yourself a favor and watch it!!
