@Cernunnos yeah, kinda similar with Miyuki dan Kaguya BUT it's the other way around. Instead of Miyuki (the dude) that became the horndog, it's Kubo (the girl) who's probably gonna devour him if they get married and finally do "it".
Rip Shiraishi's hips, at least he'll got that booty without asking, if anything she'll probably initiate most of it.
Shiraishi better works hard by then to support those children.
