I kinda forget how the 3rd season started so i just started to reread and when i saw the first pages i couldn't believe my eyes. This part must be a flash forward, apparently the dentist was arrested (will be arrested, actually) and then admitted to an asylum. I have absolutely no memory of reading this part.

The worst part is... Sejin is the son of a wealthy couple but his parents died in an arson and he was kidnapped. He has no memories of this, he thinks the guy who kidnapped him (who he ran away from in that cold night) is his real parent. The guy who adopted him also knows this but kept it a secret. Unfortunately the author doesn't delve too deeply into this story. Ido investigates it but he also keeps it a secret from Sejin because he doesn't want Sejin to get hurt anymore.
Poor Sejin could have everything but he's had the shittiest life since he was an infant. He tried to get away from a bad (fake) parent only to fall into the hands of an equally bad one.








The very best thing about this manga is the balance between them. We almost always see a dominant/asshole seme and a pathetic uke but in this one they have equal footing. I like it very much.
