Okay I let this marinate. Does he know he gave him a love potion yet?

uhh no

I'm still waiting for that to be resolved not gonna lie.

The love potion was just an aphrodisiac. So the prince was never under a love potion. That was reavealed by the antagonist in a chapter but I cant remember which one.

What? Damn bro!!! I assumed it was like a mal from descendants thing but that’s fine too I guess.

Yeah, I suspect it was like a failed ”love potion” from vibes only (I had no proof so I was waiting for the resolution).
The prince probably fell for him and MC was like ”whhyyy? Got a be a love potion cuz how could my bias love ME!?”

There is a hint that ml already have feelings towards Mc from start, the potion just made him really go for it cuz it's an aphrodisiac, it's kinda like those cliche story where Mc doesn't really know the behind the story, where the one ml likes is really the Mc and not the FML but the story shows only the surface where ml ends up w/ FML or something ╮(￣▽￣)╭
