This is like a loop. In ML's point of view, everything that happened here is something he has already experienced. But I think when he found something unusual in those repetitive events, he would do something to take advantage of it, hoping that those repetitive events would come to an end. In this, it was the Uke who was the "unusual", that's why he wanted the Uke. That's why he was always confident about what to do when he was in the dungeon because he already knew what they would face.

But the thing is, even with the Uke, everything is still repetitive, but this S-rank creature(enemy) came(it would turn into something like a ball-like, I don't know how to explain it. But that creature would be important in the story as well). It would be another unusual thing in his story. I don't quite remember everything, but Uke would die because he sacrificed his life even though ML didn't want him to do that (I think ML begged here). Actually, Uke was also hesitant because he wasn't sure if he would come back alive in the "normal world". And when Uke came back to life, everything was still the same, but with a bit of a difference this time.

(There would be parts after Uke died, he would come back(?) to the "normal world" where I believed Seme was not Hunter and was just CEO or something. And ML knew about that game, and I think the game was made by his relatives or something, in which he was the character. Not sure if this is a filler or a side Story.)

However, Uke had no recollection of everything, even these characters except the ML knew everything. I'm not sure if in this part where they would reverse their ring(?), ML would be the slave and Uke would be the Master. They would face similar events/dungeons and the one who would make Uke remember everything was the S-rank creature (the ball-like).

And the same S-rank creature would tell them that to end everything because everything is still repetitive, they had to give up their abilities (being Hunters) and become just a normal human being. This time, they would succeed and ML finally found the end of his repetitive life with the Uke. There are a lot of things that have happened, but I'm too lazy to add them lmao.
