Synopsis:

Yuki uses a dating app to look for his types of girls, makes them fall in love with him and then toys with them. He lies to his partners using the words they want to hear, and when he does the things they want him to do, the girls fall soon after.

"I want to be with Yuki-kun for a little while longer today..."

The girl this time is easy as well. On the way back after the date, they buy lots of alcohol and head to a hotel. In a drunken mood, they kiss just like that...

...is what was supposed to happen.

"Y'know, Yuki-kun. You're always targeting weak-looking girls like me to selfishly have sex with, am I right?"
"I'm like that too."
"I can't help but make a mess out of empty boys like you."

When he regained consciousness, his hands were in handcuffs, and his freedom of movement was taken away.
Assaulting him is Mii-chan, a meek-looking girl he just met...
