I feel like the same ML didn't follow the MC and it was like MC combined all the mls into one in the last arc.I'm a little insatisfied with this.

2 is ending. The ending is not my liking. But It will be different according to your likings.

the doll tho.... that ending scene for the doll is soo sooo heartwrenching criesss

The first world with Sun Mo wasn't so bad. He felt like it was all just data in the first place, and he did genuinely like Sun Mo (even if it was only due to his face) to the point where he was trying to hinder the players from harming him (and he DID believe Sun Mo was harmless, so he believed he was morally correct in siding with him). He left Sun Mo a little suddenly, but not by choice.

In the second world, death was frickin' everywhere, whether the MC contributed or not. He did seem to genuinely fall for Austin, at least a bit, though it all stemmed from his face once again. It was bound to happen by the end of the month-long task, but he ended up leaving halfway through on accident, when Austin sleepily replied to his confession. The MC genuinely regretted it, as he hadn't meant to leave yet.

It's the third world people (including me) have a problem with, as the MC essentially tricked Little Doll into responding to his confession right after promising to be with him forever. It was here that he really gained the title 'Scum MC' for the readers. Though, the players that arc were written in a way, I wanted the MC to actively kill them off. That (and Little Doll and the 'love rival') was the redeeming point.

The fourth arc was a little boring, simply because the ML was kind of boring. I love escape room games, but that wasn't fun to read in any way for me.

it's confirmed in the fifth and final arc that, after making Sun Mo fall for him in the first arc, and strengthening the ties in the second arc with Austin, the Boss' data, once retracted from the world, was infected upon reuse, thereby causing future incarnations to feel the attraction and possess the occasional memory the previous incarnations did. This was only possible because the MC chose the bosses who had the data of the main system.

Why did the author feel the need to have the vanilla main system cause the apotheosis of the cute and serious Sun Mo, the reliable and smart Austin, the adorable and tragic (no thanks to our MC) Little Doll, and the, uh... boring and slightly pe*verted fourth guy I don't remember the name of and Austin-like fifth guy who started off the fifth arc, fusing them with him and essentially denying their individual characteristics that made the readers fall in love with them in the first place?

What the MC and the main system ML end up doing in this is what the villain ex-MC and his system were wanting to do in that. I don't care about the last two, or the final system or whatever, but Sun Mo, Austin, and Little Doll were very interesting, very different characters, and their final ending was to disappear. They may be inside the main system, and maybe they're happy like that, since the main system is always with the MC, but as a consequence, their names, faces, personality, and general sense of existence was straight-up killed.

The ML is a Multiple characters with different Data that infected by the first two MLs' data aka their Love toward the MC. But no worries, MC found a way to make their Data turned into One Body.

Because Usually in other Isekai World Hopping Novel, the ML always has the same Soul in every world.

The most annoying thing for me, was that every world was set up to try and move the protagonist away from being a facecon. Like, to help him develop a deeper love. But it plain never happens. He acts like one in love, but it's always about the face even at the end. What's the point of setting up every world to teach him that lesson, only for it not to matter at all? The author must have gotten really bored of writing this in the last arc.

Doll Arc: Great arc, but the ending is sad. MC tricked ML into saying, “I like you” only leaving the ML 30 minutes later. It broke my heart. MC saw ML suffer after he was gone. He cried for a few minutes or something like that before going to a new world go hook up with another ML.

If he have s*x with ML then ML will let him pass through. WTH?
