Ohhh, that's adorable, honey! Glad to know you were so invested!!

[Suddenly his opinion of Papyrus is boosted. Anyone who takes that much time watching his shows immediately matters that much more to Mettaton.]

I apologize, but I don't remember any of that. Though if you like, I can take you out for coffee again! Consider it an apology for not remembering such a handsome fellow like yourself!!

[Mettaton has never had coffee in any real capacity. This may not go as well as Papyrus would hope.]
