Read till chap 66... Just because I liked the GIRLS only.
Boys, dont take after this mc, such a guy with zero self confidence, he doesnt trust himself nor the girl he likes. Also he dont have any courage, the black haired girl (Akai's girl) said it all what is true to him in some chapter I dont remember, this guy isnt a man at all, just a simp, or not even a simp, because when the girls (Hayamine included!) go after him and WANT IT, he turns into a shy virgin.
Ah, I dont like NTR at all, but think if it story was with real life people, he would get ntred by the girls long ago, the patience the girls are having in this story (waiting for him) is just utopia, doesnt exist.
