Prompto runs out of suppressants or his heat comes off-schedule because of the stress of having the empire on their tail, and Aranea offers to help him through his heat.

Bonus points if one or more of the other boys are alphas and jealous that Prompto would rather get help from Aranea than them. (Maybe he's afraid it'll affect their friendship or that they'll see his barcode tattoo?)

please I just need more female alpha/male omega in my life
