good chapter, there is a lot to improve, but still, good chapter, and since apparently the "mc" wants a harem, and he will need it for being a hamon user (if you understand), but for the attitude / character Of the girlfriend of the "mc" it is unlikely that this would allow him to have a harem to the "mc", then the "mc" would have to dominate his girlfriend and have as much *** with her, like 10 times every day, for this Accept that she alone cannot satisfy him and that if they continue like this, he could kill her for ***, besides that the "mc" could whisper to him what it would be like to have a threesome or foursome, etc with more women, awakening desires in his girlfriend and stuff, like that being able to subtly convince her that a harem is necessary.
