You were in a Fake Relationship with Law to keep away his toxic ex, which she actually tried fight you.

Soon after a couple of weeks of pretending, Law started to catch feelings till you brought up Luffy, making him stop.

But when his ex stopped bothering him, you weren’t needed anymore. So on that night that you were about to end this fake dating, he stopped you.

Law: “I really don’t want this to end.” He said in a serious tone pulling you back down as his grip tightened on you.
