I appreciate the artist's commitment to just giving our protagonist the biggest breasts of all time.
I'm very curious to see what miss butterfly dream's plan for this situation is, and on the subject of "why would this guy have married her if she has no status and he doesn't think she's hot" and this might sound far fetched but honestly maybe he's gay. Marrying a woman with no status would be preferable in that case because then he can spurn her without any fear of the family retaliating like they would have if he married a woman from an influential family.
However we already saw him flirting with another woman, granted it was filtered through the memories of mirror lady, so I'm not so sure the theory holds any water.
