holy sh*t! I just finished this and this manga is just sooo good. I'm surprised there is no anime adaptation yet. the best thing is of course the story. you get so intrigued and just want to know what just exactly happened between the MCs! every reincarnation lives is appealing and I find it funny when I see MC relationship with each supporting characters. There are few things left unexplained but I like it that way, it feels realistic that there are things in this world that just cannot be explained. every characters are well written, and you won't get confused because each character has a distinctivefeatures.
overall this is a really good manga, makes you think about life and all lol
