Lucy, and he entrances her.

"Alright Happy, I'm going to Lucy's," Natsu said.

"Okay, that sounds fun! She reacts so funny when she sees us in there!" Happy said casually.

"Yeah, it's odd, like she's not happy to see her friends," Natsu chortled, also enjoying the humor that came from Lucy's "strange" reactions. They left the house, casually walking down the street…

…

"WHAT THE HELL ARE YOU TWO DOING IN HERE AGAIN!?" Lucy shouted comically, her eyes bugging out. She had just walked out of her bedroom to find Natsu and Happy chilling on her couch.

"Chilling at a friend's house, is that a problem?" Natsu snarked.

"IT IS WHEN SAID FRIEND DIDN'T INVITE YOU, YOU IDIOTS!" Lucy shouted, before grabbing Happy, and chucking him out the window, the cat flapping his arms comically, as if forgetting he could turn them into wings.

Lucy then turned to Natsu, ready to do the same to him, before suddenly having a blank expression on her face. Natsu chuckled, reviewing what he had written in the Note, "When Lucy Heartfilia finds Natsu Dragneel and Happy in her house, she will throw Happy out, who will wait for Natsu outside the house. She will then enter into a mindless obedient trance that Natsu will be able to program her in, placing subliminal commands in her head, along with triggers, and these commands will stick around and be obeyed even after he wakes her."

He then gazed at the blank Lucy, already considering what to do with her.
