I have another manga that I have thought about and only recently remembered it but as much as I remember it was about a girl who I think sent a mail order to get a boyfriend that was curated to her. I know it's not Absolute Boyfriend because the art was unfamiliar but it had that concept. I also remember with the male lead, there was like a mixup that the male lead was actually not supposed to be with that girl but the girl didn't care because she really liked him. Again not much to go on but I remember it being within that sector.

is it My Sweet Honey?, perhaps?

Be kind or get banned

I don't think so because the couple didn't change and stayed consistent. I do remember that the leader to the mail order tried to set her up with different "made boyfriends" but she refused and the male lead kept going back to her as well. The second female lead or the one that was supposed to end up with the male lead had long black hair. Maybe with bangs?
