[Heizou's smile grows, mischief back in his face as he leans in real close.] Hmmm... Something tells me you might already have an idea what color he was after~

[He pulls back after giving Aether a little boop on the nose, only to start circling him where he stands like a shark. It's all playful and teasing at least, the delight on Heizou's face completely genuine.]

I wasn't completely certain of it myself until your reaction just now. You're quite famous and well connected, you know! It stood to reason you'd be well acquainted with more than one of the Fatui Harbingers, and given your penchant for influencing people around you for the better I thought to myself, "Wow! Surely only someone like our esteemed Traveler could earn the love of someone with his colorful history!" And then you appear, sporting some quite distinct love marks and a familiarity with these magical chocolates. Ones that our favorite harbinger, by his own admission, had eaten his full of yesterday...

[He pauses there, mostly for dramatic effect, but then he leans into Aether's space again with such a shit-eating grin across his face.]

You know I don't believe in coincidences. So tell me, my dear friend, what kind of conclusion do you suppose I've come to~?
