I love plots like these but man is it so overused like the author didn't even try to make the isekai part of it interesting he just put it there for the sake of adding the tag it would've been the same if not better if it wasn't under isekai such false advertisement
Also the somnophilia scenes WERENT necessary like bro it wasn't romantic, and important to the plot the ml had such a good character build (referring to when he believed the Mc over his cousin at the library scene) BUT HE JUST HAD TO BE INTO UNCONCIOUS SEX EWWWW
Sex with the Love Interest! But I'm an NPC!
