You mean does the mangaka have a fetish for woman with a virgin fetish.. and to be c*ckblocked an incestuous past.. he's got some serious issues and hang ups..
@SuperOniichan not the MC, the guy that Miyoshi took to the hotel. did you read a different chapter to me? https://mangadex.org/chapter/1080391/15
he literally says "I've experienced this before... thought it was my mama (I believe this is a typo - it should be THOUGH)." because in the next page she literally calls him a mother-con (ie someone with a mother complex - just as in Japanese people with lolita complexes are loli-cons and shota complexes are shota-cons).
