And fun. It's like yuri potato chips. You read this and its insanely stupid but you can't help but root for these dumb lesbians. xDThe harem...grows.
This series is delightfully dumb.
100K + room and board and food that's a pretty good deal for a live in gf100k yen/month is super cheap. I forgot how much Chie has left but assuming she put 50 million yen in an average index fund at 6% yield, that's an annual return of 3 million yen/year or 250k yen/month. That's more than enough to pay for her sugar baby without lifting a finger (even accounting for food and utilities).
