The more I read, the more I pity the MC. All his life, he's been robbed (of his parents, normal life), took advantage of and used (by the shitty congressman, the blondie gang leader) and now caught by the ML. The reason the MC's hypersexual is because he's been trained/sexually coerced, manipulated since the young age by the blondie gang leader. We see in the early chapter that the MC use sex to complete his "missions". Probably trained by the blondie gang leader - his Hyung along with the need to pay off his debt to the shitty congressman.
I have a wild theory. Maybe Jian is not biological child of that witch, but Hajoon is. She and president Yang switch their sons for some reasons. That would explain why that witch uses drugs to keep Jian under her control, and why Hajoon detests Jian and Jitae because he's jealous.
President Yang is the grandfather's long-time subordinate. The dude was being kicked by the grandfather at the restaurant where he supposed to meet Jitae in chapter 14. At first, I thought Jian's real father is the grandfather, that would explains his tolerance to that witch. But now I thought maybe that witch is his illegitimate daughter. Jitae's father just kept quiet for the family's reputation and wanted send to Jitae's mom from that messed up family.
That Hajoon punk and Jian's mother have the same hair color, and they kind look alike. Could it be he's her relative?
I wouldn't put it past that Hajoon bastard. By the way, I think President Yang - Jian's biological father is the grandfather's long-time subordinate. The dude was being kicked by the grandfather at the restaurant where he supposed to meet Jitae in chapter 14. At first, I thought Jian's real father is the grandfather, that would explains his tolerance to that witch. But now I thought maybe that witch is his illegitimate daughter. Jitae just kept quiet for the family's reputation and wanted send to Jitae's mom from that messed up family.
Suryeon is just some power hungry woman. Her only relationship to the grandfather is through his now deceased son, president Baek, and Jian, a father and son tie. But it has now been revealed that she lied about that so the deceased president baek is not really his father! Which is sad because his marriage with Jitae’s mom was ruined over nothing! The grandfather only tolerates her because she knows and done too much that could ruin the company if it ever gets revealed. Including, Jitae’s mother’s murder! Which is why the grandfather gave her his dead son’s old position as president! That position was always meant for Jitae and that’s why it was vacant for a long time, until Suryeon got caught in the act of killing jitae’s mom. He wanted to put a leash on her with the thing she covets, if that makes sense.









He bugs his phone????? Wow, so he already suspects him might betray him from the start and take precaution?
Or he’s THAT yandere/possessive
