The suicide was before he joined the competition. Since MC woke up in someone else's body and then was forced to debute or die according to the system. You might want to reread for details.

Why would he not kill the guy who knows so many of his secrets?? He's killed people for way less.

Oh boy oh boy I can not wait to see the door of blood opened.

Hey Red Dragon X Healer Elf was an adorable pairing and I don't want it wasted on some generic harem comedy

Well they asked

Slowly the past is being revealed in flashbacks, but the girl who originally broke his heart because she tried dating someone else to gain experience because she was too nervous to go out with him directly got hardcore bashed in an online post claiming she was asking out (and presumably sleeping with) ever guy she could find. The MCy wrote a fake anonymous post claiming that the bashing post was a bunch of lies he made up to slander her since he was rejected. That way he'll be villainized instead of her. And now we're about to hear about the actual past.

Ah yes, I think I only read a couple chapters of that.

What was it?

Singing Sweet Home Alabama all summer long

The giant dude with the monk. He's in a state of half death cause he's similar to the undying corpse guys. The person attacking the girl is the son of the Morong patriarch which was the first person the MC destroyed after venturing to the mainland.

Very first few chapters, his friend who was dropped off a cliff by the Envoy who came to kidnap the girl who was with them.

Probably he can since he managed to teleport here.

I suspect poison on the sword. Or something else dangerous.

My brainrot girlfriend

White people who took over Africa. The English.

You mean the english?

The beast unleashed.

Would be happier for sure. Sometimes in these stories the Ex-gf is basically a monster and it's like "I don't want them to reconcile" but in this story everyone is just young and awkward and regretful that they hurt people they care about which is the perfect set up for redemption and reconciliation.

Don't get me wrong it's definitely a better story for him to be reconciling with his past and delving into how easily it can be to accidentally hurt others, as well as yourself. And the cast still interacting with him is what drives the story.
But still if he never saw the two girls in highschool perhaps he would move on since he has his new ikemen bestie and the college basketball friends.
It wouldn't be the same type of closure as he'll get from the current story, but I think in life sometimes we get hurt and then we learn that we can move past it.
Of course the reconciling with his family might not happen if he doesn't reconcile with his friends first, or maybe it will be delayed by him focusing more on the girls than his Mom and Sister. Of course this is just a story, but life is like that where you never really know how things could be different if just one small thing was different.

Honestly it feels more like being surrounded by reminders makes it harder for him to move on, rather than easier.
