I don’t hate MC But it was kind of hard to root for him, knowing that he was only doing ...

The role he stole was meant for him. The screenwriter wrote that character thinking on him. And I think his behavior was well portrayed. He was a bad person, but after he realized how bad he was with other people, he redeemed himself.

Understandable but couldn’t that be said to every bad person ? like if all the bad people had a second chance to go back in time, of course they’re going to try to be good people. He literally Bullied someone into committing suicide . If his mother had not sent him back in time, he would’ve died a horrible person just saying

Yes, of course, what he did was horrible and he deserved to suffer and pay for his actions. But it the end this is a story of second chances, and it's not like he didn't suffer in his first life ^^'. Even in this new life he has to work hard, it's not like it's a bed of roses. He has to overcome obstacles to achive his goals and happiness. But this is only how I see it, of course I get your point and I understand that you don't like him :)

i think we'd be surprised, he could've been a worse person but better equipped. doing a 180, realizing your faults and trying to better yourself is hard, really hard

Not true lol
Some people are simply JUST bad people. Even if they saw the future they wouldn't go back in time to fix it. And although he did bad things...the MC himself wasnt a bad person. With the way his mother loved him and the literal flashbacks we saw, he wasn't always like that. And because of reading we know he did those things out of his obsession/"love" for the shitface.
Not justifying his actions, but just saying. There are GENUINE terrible people on this earth and they would NOT change who they are because they think they're better than everyone
