MC thinking the current Terry regressed 17 times but the one on this timeline has already regressed 117 times. So he’s waaaayyy stronger than the evil Terry (antagonist).

Yes, this is the correct timeline—the 17th timeline. However, it’s unique because the current Ailette exists in it. This is the only 17th timeline where the current Ailette is present.
As for Terry, he regressed from the 117th timeline, traveling through each one to find Ailette. On the 17th timeline alone, he regressed three times:
1.First Regression: He was killed by Reid.
2.Second Regression: After discovering that Ailette wasn’t in this timeline, instead of being killed by Reid, he proceeded to the 18th timeline. By this point, he had already reached his 100th regression, and it was the last time he was still human.
3.Third Regression: He became the current 117th Terry, which is where this timeline, with Ailette, takes place.

He’s fully aware of the regressions. The current Thesilid is in his 117th regression, far more advanced than Reid.
Thesilid, at one point, became Reid and attempted to destroy the world, but he failed and was imprisoned by five powerful individuals. Since he cannot die permanently and will just regress, they gave him a punishment: imprisonment in the abyss (or a similar place). There, he was repeatedly killed and brought back to life using the Water of Life—or something similar.
The Water of Life extends a person’s lifespan but shatters their mind, causing severe illusions, memory loss, and other psychological torment.

Ailette, the FL, accidentally ended up in the dungeon where Reid was imprisoned after visiting the VIP shop. (Refer to previous chapters) There, she stole the regression artifact (the one that looks like diskette for saving) and unintentionally freed Reid. Shortly after, Reid killed himself. Ailette didn’t realize it was Reid because he was referred to as [Fearless], and she didn’t actually see him as she left the dungeon quickly. After Thesilid (Reid) died, he regressed all the way back to the very beginning.
The repeated use of the Water of Life caused severe side effects, including memory loss. As a result, Thesilid believed this was his very first regression. However, his past self (Reid from the 100th regression) kept appearing and killing him repeatedly.
By the 17th episode, Thesilid and Ailette finally met again. Around this time, he started recovering fragments of his lost memories, though not all of them.
It is quite confusing tbh but I hope you got my point. ( ̄∇ ̄")

Your explanation is fine, I understand it perfectly. Thanks a lot for taking your time to explain it. To summarise it,
-Thesilid already went through 100th regression,
-became Reid, attempting to destroy world,
-imprisoned in dungeon(punishment),
-Ailette unintentionally help freed Reid(Thesilid),
-then he regress back to the beginning with memory loss,
-then he meet Ailette again in 17th timeline(while recovering his memories) which is the current timeline in the manhwa now.

This manhwa highlights an important aspect of toxic relationships. How women often stay because they cling to the memory of their partner’s good side. You convince yourself that the person you fell for is still there, holding onto hope that they’ll return to who they once were, even though they’ve clearly changed.

I just scrolled up without reading. (╯°Д °)╯╧╧
I knew it’s gonna be that carrot hair’s backstory!! No matter what, he’s still an a$sh0le!

He doesn’t have the commitment, girl! My grandparents on both my mom’s and dad’s sides grew old together, standing by each other through everything. I believe that if you’re truly committed to your partner, it doesn’t matter how many years pass or what challenges come your way—you’ll never stop loving them. True commitment is about choosing each other every day, through the highs and lows, and continuing to nurture that love as time goes on.
But as you said, it’s scary now and that’s why I’m still single. ╮( ̄▽ ̄)╭
The real world is the ABO world.
Their first life is what Heemin considers the "novel" world, but since everything was traumatic for him he creates the non-ABO world to cope. Hun somehow ends up there with all his memories and tries to be a better person to Heemin who doesn't remember their first lifetime/real world. Then they end up back in the real/ABO world, but back in time to when things first started going bad between Heemin and Hun. Heemin thinks the non-ABO world is the real world and the real world is the "novel world". Hun eventually remembers everything, both their first life in the real world and in Heemin's non-ABO world but doesn't want Heemin to remember their first life. They're both trying to make the current timeline/life better. Hence why things are different and certain plot points are either coming up sooner/being resolved quicker.
I love this theory
This is a novel spoiler. (≧∀≦)
