Warehouse
At the end of part 1, here's a summary : Dohyun was kidnapped by Sungho. We discovered that they used to have a sexual relationship back in high school which consisted of Dohyun demanding only sex : Sungho didn't want it but still let Dohyun fuck him because he was desperatly clinging to Dohyun (obsessed). Dohyun ended this relationship, which was taken by Sungho as being abandoned. Fastforward 9 years, Dohyun in at Sungho's mercy, raped regularly in a warehouse recreated by Sungho to look like their high school gym and sexual meeting point from back then. Dohyun has a hard time remembering people and events but ends up remembering Sungho. He realizes each rape is a simulation of a sexual encounter they had, but reversed (Dohyun is getting fucked). By the end, coworkers of Sungho break into the warehouse and scold him for his behavior and sick/twisted game, then get into a fight with him when they hurt Dohyun (I should read chap 35 and 36 to remember the scene). They leave and Sungho takes an unconscious Dohyun and escapes with him. Other facts : - Sungho has a scar which we don't know the origin of for now. - He works for a shady business. - He is obsessed and certainly in love with Dohyun, and has mixed feelings between revenge and ownership (he wants to keep Dohyun to himself and can't bear to kill him even if he's thought about it. I think he's pathologically obsessed with Dohyun and wants to hurt/torment him for leaving him in the past, but also to control him and make sure he doesn't escape. He's obviously sexually attracted to Dohyun, although it's not clear if he was in the past (high school time). He hasn't let go of his feelings, which are a painful and twisted kind of love for Dohyun. - Sungho had/has a sickness which used to send him to the hospital (mental sickness ? something else ?) - Dohyun has memory issues (accident ?) - Dohyun isn't in love with Sungho (from what we've seen until now), as he taunts Sungho, saying their relationship ended a long time ago (didn't mean much to him). By the end, he's mentally exhausted and asked Sungho to kill him. I'd like it if in part 2 he fell for Sungho or had some feelings for him, but I kind of think it's doomed.
