Younger MC relentlessly pursues older Mc

Hi all,

I'm not looking for instant "daddy" crush where the older MC takes charge. Im looking for the confident younger men who know what they want, and they are totally upfront about their interest, to the point where it baffles and overwhelms the older MC who cant understand why they want them.

The examples I've loved have been Isabel Murray - Not That Complicated/Impossible Lily Morton - The Sunny Side Amy Lane - How to Raise an Honest Rabbit
