It's so funny that these girls holding their promises with him while this guy just easily forgets them like it's none of his problem. At least remember a bit...
Actually if most of us thought about it... most people had more than one girlfriend before settling down, a more realistic manga would be very red pilled when at a younger age thinking they can improve on their partner options in most cases.
@ekattor yup, i can confirm 3 girls will end up liking him for now at least
@John_Doe_Jersey ,the harem appears to look good in the novel,in the manga, there are so less pages and such weird art ,i am not sure showing it here would be a good idea, it should be monthly serialized and have good art to make it look alright/good
