"I might become an experimental subject again."
I don't remember him ever talking about being reincarnated to his mom. Am I just not remembering everything?
Damn.. Every manga or anything i read, there always someone that think every woman that friendly with MC should be with MC and said MC doing cuckold if they are not become heroine. This type of people always insufferable, they should just stick to harem genre where the MC pick up any girls they find.
