Another reason why the hero should forget about his ex wife and move on. Minako doesn't like dressing up in sexy cosplay, she hates toys, and DVDs. She finds Yuuto a creep and perv; I bet she moved on.
I think the only reason he's hung up on her now is because he realizes that what he's doing isn't a whole lot different than what she did to him (magical compulsions aside). So he's feeling guilty about that and it's manifesting as thinking about her more.
she's just a bitch bro forget about her already. i don't think this author knows much of anything about how lactation works. then again he does admit that this is all just his porn knowledge so i guess it's okay he doesn't know anything about what's taught in middle school biology.
