The early chapter where the MC had s3x with the bakery mom, and I thought it would progress as romance since they show affection after they did it, but sadly no... A sudden Jose dude approached Marie (bakery mom), and she suddenly fell in love lol. As the story progresses, the MC becomes more like a business partner for Marie, and he even helps this Jose dude on how to flirt with Marie. In the raw, Jose and Marie look like they started dating? since they always meet up and he always invites her to have dinner/go out. Also, since Marie started seeing this Jose, she's taking care of herself now by using makeup and changing her hairstyle (looks like the author is going to ship sailing those two and just forget about what happened in the early chapters).
As for the MC, why I said he's being pathetic coz he's acting like getting jealous in the early chapter after seeing Marie and Jose close to each other. There is also a scene where there is another dude (Mark) who is in love with Marie, and got mad at the MC coz he's being close to Marie (he punched the MC in front of the girls, and ofc MC's harem fight back for him, one of his girls smashed this Mark and brutally killed him, but the MC is "saint-like" and suggest the fairy girl (the one who killed Mark) to heal him up coz he doesn't want some trouble lol). In a further chapter, this Mark kidnapped Marie and attempted to grape her, in ch. 39, where the MC and his group are trying to rescue her, but all this "rescue doing" is done by his group, and the MC can't even hit a single guard... His sister is even stronger than this pathetic MC. The only good thing about this MC is that he has an isekai skill where he can buy things from Japan through an online store, and he is just a "d1ldo thing" for his harem.
