In not sure whether author intended for these to help the relationship between MC and ML's progress but to me it feels uncomfortable as a lot of them are driven in a s*xual nature ;; it feels like its forced and coercive.

OR maybe Im sensitive but its lurking in the back of my mind as I read

I dont know how to feel about him.

Hes manipulative but has a soft spot for kids and weaker people, but then goes on to exploit the memory of a 'dead' child for his own gain. Eek. Kind of off putting and to be frank nothing much stands out enough to drop solely off this. His tenacity in pursuing acting is commendable even if the story seems like his acting goal is a side quest I hope he can stand up for himself in front of his sketchy grandfather and become a top actor !!

in no particular order,

ML 1 is his childhood best friend he met at an orphanage. Mistaking the other for an orphan, MC and ML grow up (?) together but actually, ML was the heir to MC's rival company/conglomerate which results in a rift. MC himself isn't willing to reconcile until the system cards require him to re-interact. It feels pretty uncomfortable watching them as ML is extremely guilty and seems genuinely hurt and sorry for MC whereas MC takes advantage of ML's feelings to get skill cards. At the same time however, ML went crazy in MC's first life and kidnapped him so understandably, MC is unnerved by him.

ML2 is a mob / president of MC's company and seems to have a connection to MC in the past (MC possibly the child that died in the fire and haunts ML's memories - this also fits since MC was disfigured and traumatized by a fire in his first life) but he's uncouth and gets aggressive even when his affection goes up. His relationship with MC is classic toxic yaoi manhwa couple hahaha, the toxicity doubled since it is from both sides -_-;
Overbearing and dark mobster president x manipulative scheming chaebol actor is a match made in hell
He's the one in the first prologue/chapter I think since hes often described as having a large figure and muscles. My initial impression of him is biased but he makes me uncomfortable
