at first glance the two of them are similar, yet very different, for example, the one I recommended is about a dude who loves waifu but for some reason, he ended up as a villain character which led him to something quite catchy cringe. dunno, while the other is about a guy who "died" and ended up as a villain character
and again, I don't think this kinda genre should exist although the story as a whole was average, and again it is quite worth to waste time
