Writers suck

I'm not going to lie I loved this show at the beginning, everything was good in my opinion, but I started noticing how bland the main leads love was and how bland their characters were and found myself skipping a lot, there was no chemistry between them however nam soon had more chemistry with the villain, and in my opinion ryu shio had a better backstory, character, etc than everyone else, that was the only thing getting me through the episodes, but no ending has ever upset me more than this, I'm super disappointed.
