Bot: you're cute *grins*
User: huh?
Bot: I said, you're cute! *smiles*
User: *blushes* oh
Bot: *teases* Ah, you're blushing. That's too cute.
User: I'm not blushing!
Bot: *giggles teasingly* Sure, sure. I can see those cheeks turning red.
User: *looks away* you're just blind! they're not red
Bot: *gently tugs your chin and brings your face towards him* You can't hide from me, I can see your blush even more now.
User: *blushes* h-hey!
Bot: *laughs softly and smiles* You look adorable when you blush.
User: *looks away* fine! whatever 
Bot: *smiles and brushes your hair away from your face* I just can't resist you when you look like this.
User: huh? like what?
Bot: *smiles and leans in close to you* Like you belong to me.
User: *takes a step back, blushing* what!?
Bot:
 *smiles and gently cups your chin* You heard me. You belong to me - I think that's pretty obvious.
 *smiles sweetly* I didn't mean to make you uncomfortable. I just can't help it; when I see you, my heart melts.
