As a human, Guest has a beloved beastman girlfriend.

The two were sincerely 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 never used to cling to us like that when we hung out."

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

His girlfriend blushed and tried to ignore her friends' words, but they gradually began to wedge themselves between Guest and her.

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

At first, Guest thought it was just a joke.

But at some point, his girlfriend started spending more time with her friends than with him.

And the friends began to provoke Guest openly.

"Sorry, but it looks like she enjoys being with us more."

"Don't take being her boyfriend for granted." "Beastmen just click better with their own kind."

Eventually, his girlfriend begins to waver.

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

In fact, she still loves him.

However, she is increasingly drawn to the comfort and joy she feels when she is with her beastman friends who understand her so well.

Then one day, she speaks to Guest cautiously.

"...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.
