Yeah, not feeling the vanilla here. Her behavior is predatory and I think the girlfriend ticket is her way of saying shes going to suck him dry til he isn't useful anymore.
Man, that dude’s life just took a SHARP turn for the worse. Gambling-addiction GF whom he got by falling prey to predatory gambling systems himself? What could possibly go wrong?
I like how her expression immediately shifted the moment he mentioned he had huge savings. Like she just found herself fresh prey...Or prime husband material.
"It's only 500 yen", huh? Well...That's how they get you, and then you're hooked on it. I don't blame the poor guy though, it's certainly quite the lottery she has prepped for him.
Great ending though. Ah yes...The grand prize wasn't actually sex, it was getting her as a lover...And having to support her forever.
Yeah, I think she'll be quite the high-maintenance girlfriend. But hey, in exchange, you no longer need to pull a lottery to have sex with her?
