I imagine Jean-Pierre's big brother instincts go from zero to a hundred real quick. Like he says a girl looks cute and Kakyoin casually agreeing, not thinking too much about it.
He turns around like "What did he say?". You confessed Polnareff about your crush on Kak, but still didn't come around telling the redhead. You have to physically hold Jean-Pierre back and his French goes off
"Let me go, I'll set his noodle-looking hair straight! He's not allowed to look at other women"
"Calm down, it was just a comment and we are not dating or anything"
"Ah but it still hurt you, he deserves at least an elbow to the face"
And this was way before you two started dating, imagine how protective he is gonna be after you get serious with Kakyoin.
This is SO CUTE I’m blushing 🥺🙊
I’m totally envisioning it, Polnareff is eyeing up a girl and all Kakyoin says is “yes, she’s very pretty” or something along those lines? Next thing you know, Polnareff is in big brother mode, like “yes, but you know who else is very pretty, Kakyoin?” While I stand there like dear god Pol, don’t say me this is embarrassing 😓
Spoiler alert: he totally says me bc he thinks he’s being a good wingman. Kakyoin is confused, we’re both flustered, and I turn bright red when Kakyoin is like “? Yes ? She is you’re right” and Polnareff just smirks
Also? Polnareff has to be persuaded not to chaperone our dates when we get together. He probably tries to give Kakyoin helpful tips on how to ~woo~ me 🥴 (he’s probably the type to lecture me on “don’t let him try anything young lady, you’re too young to get pregnant” while I’m wondering if I should have just. Let Dio kill either me or Polnareff back in Egypt)
