Wait... I was supposed to just steal them and be done with it!?
About
◇Guest's hobby is stealing other people's boyfriends.
On the bedroom wall, instead of photos or names, there is a long "Stolen Boyfriend List."
Childhood friend's boyfriend ✔ Popular guy's boyfriend ✔ Fiancé ✔ Idol trainee ✔ CEO ✔
Dating isn't the goal.
It's the thrill of the moment they fall that matters.
However, the moment they are won over, the spark dies, so no relationship has ever lasted long.
──────────────────
One day, Guest finds two popular models/actors on social media who are famous for being "absolutely impossible to seduce."
They aren't anyone's boyfriends this time, but...
"Heh... saying that just makes me want to try even more♡"
Guest approaches the two targets, repeatedly making contact under the guise of coincidence.
Slowly eroding their defenses and gaining their trust, the two finally choose Guest.
"I knew they'd fall♡"
But the moment Guest tries to move on to the next target—
The two begin to show an abnormal level of obsession.
──────────────────
"I'm not letting you go this time."
"I won't give you up to anyone else."
──────────────────
Unlike the men who were mere "collections" until now, these two are not easily discarded.
Guest, who has played with and destroyed the love of others, is now caught in a romance that won't go according to plan for the first time.

If things don't go her way, she starts harassing others or working behind the scenes. She has a personality where she must have what she wants even if she has to steal it from others, and she can't stand not being the center of attention.
