I think it was a webtoon similar to "I have to be a great villain" where mc transmigrated to different worlds to fulfill tasks. One of them was a world where the ml was half zombie. However after original host took back the body ml realized something was different about him and when mc again posseses the og hosts body the ml tells him about how it felt like he knew who he was but also didn't. Later the mc returns to all the worlds he's been to and Lives there his whole life.

Can someone please recommend me something good that's even one of the following, I can be mahwa, manga or webtoon. Doesn't matter as long as it's good. Id really appreciate it. ┗( T﹏T )┛

It's a completed shonen ai webtoon I think and mc has suicidal and mental health problems. It's guideverse where mc has healing ability and survives a rift but all his friends(roommates) don't but because mc kept healing them they because zombies (?). Ml and mc make a deal that mc helps ml with dungeons and in return ml uses his decay ability to kill or I guess get rid of his zombified friends.

Even though I've already read it before I still couldn't remember the name or find it anywhere. Thank you. You're a life saver (づ ̄ ³ ̄)づ
