Review Detail of SHIN in I can see others’ information!

Author I have a question to ask you is MC going to have his mother in his Harem or not?After reading chapter 1 to 11 I liked how the Author developed the MC and i have a very high expectations of chapter 12 due his anger, but i really disappointed with it because basically MC just said both of them are cheating with each other and he is leaving the house, i hoped there is some kind of drama but chapter 12 is really disappointed me.(When i read the novels name i thought it's a novel where the MC is some kind of villain and use his cheat manipulate other's but his friend is NTRed him with his own mother and MC is not going to get his revenge for that? I choose mother and son inc33t rather than family members NTR)
