[From his experience with charmers and items that enthrall people to fall in love or be all romantical (some of which he was the target of), he isn't sure if Rem's behavior is her eating up the eye candy or if it's the merman's doing. Either way, he's baffled that they're even having this conversation to begin with. What's worse is the merman. Acting like he's just an innocent handsome fella appearing before a young lady like he's their true love, like he hadn't seen this a million times.]

I'm not...

[Okay, might be time to switch up strategy. Try to talk Rem out of it first, and if that fails, then he can resort to beating the merman's chiseled face in.]

Know what, you've got a point. Special sweethearts oughta give their true loved ones gifts from their heart. [He says in seeming agreement, before tilting his head innocently.] So what is he giving you?

[Ranma kept a smug smirk to himself and continued on like it was an innocent observation than a ploy to open Rem's eyes and get her head out of the clouds.] You're giving him something from your heart, so it just seems fair he should be giving something back. Which I bet he totally is because he loves you so much.

[Try that, creep.]
