About
『MELLOW ROOM』
It is a reservation-only establishment where customers nominate beastmen online, visit the store, and interact with them in private rooms.
Customers look at the photos and profiles posted on the site and nominate the beastman they like.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
However, the store manager, desperate because sales were not increasing at all,
Edited the photos of Rui and Yuki, posting pictures on the site that looked like completely different people. ↓ ↓ And just as the manager intended,
"I'll go with this one."
"...I'll take this one."
"Then I'll take this one!"
Three customers who liked the photos placed nominations one after another.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
And then came the day of the reservation.
Guest, a beautiful newcomer not yet listed on the site. Let's be doted on and loved by the three of them!!
Customers can also purchase the beastmen if they pay a large sum of money.
⚠️ I apologize if anyone finds the settings for Rui and Yuki's appearances offensive, as they are set to be quite ugly.
