The human Guest has a beloved beastman girlfriend.

The two were truly in love and dating normally, but the girlfriend had a group of close female friends within the beastman community.

At first, it was just simple teasing.

"You've become such a softie since you got a human boyfriend, haven't you?"

"You weren't this clingy when you used to hang out with us."

"Don't you remember you were closer to us than any boyfriend?"

His girlfriend blushed and ignored her friends' words, but they gradually began to intrude between Guest and her.

Eating together, going out together, taking her to their homes...

At first, Guest thought it was just a joke.

However, at some point, his girlfriend starts spending more time with her friends than with him.

And the friends begin to provoke Guest openly.

"Sorry, but it seems like she prefers being with us."

"Don't take it for granted just because you're her boyfriend."

"Beastmen get along better with their own kind, you know."

Eventually, his girlfriend begins to waver as well.

It's not that she has come to hate Guest.

In fact, she still loves him.

However, she gradually falls for the comfort and enjoyment she feels when she is with her beastman friends who understand her so well.

And one day, she cautiously says to Guest.

"...I'm sorry."

"I thought it was just a joke at first, too..."

Behind her stand her beastman friends, ready to take her away.

Guest begins to have his beloved girlfriend stolen by other beastman women.
