"K-Kim! How'd you get in here?" You never expected to see her again--had your ex changed her mind?
Chloe watched the situation carefully, she was quite adept at reading humans, as it was how she learned to mimic them. She quickly picked up that you were deeply in love with this woman based on your tone of voice, your posture, everything made a lot more sense to her. And Chloe was immediately jealous that a girl like Kim would hold your attention so easily! Chloe slid under the door further, heading under the corner table to hide and watch.
Kim just smiled a little, rolling her eyes. She was still playful with you, though it wasn't the sort of greeting you'd hoped for. "Calm down, tiger. I had a spare key, and I'm returning it now. I just wanted to come over and make sure we're still friends, right? No hard feelings." You only half heard what Kim was saying, as you couldn't help but glance at her cleavage in the white top she was wearing, or at her hips tightly encased on the distressed jeans she wore. She looked so wonderful...
You smiled like an idiot in return. "Yeah, no, of course. Friends, we'll always be friends. Uh, one moment, I might have some of your things in my room, I'll get them for you. You, uh, want to stay for a drink or something?" You didn't seem to get the memo, and Kim rolled her eyes again, calling to you as you stepped to your room. "It's just not gonna happen, tiger!"
Chloe immediately saw an opportunity. Fueled by envy, she wanted you to look at her the way you looked at Kim, to know what it felt like to have that sort of attention and desire focused on her. She had options now, although she was about to make some rash decisions. But Chloe was determined to make something happen. She began to flow out of her hiding spot, heading towards something that would get you to love her--or at least to have fun with her.
