My Poison Princess Is Still Cute, Vol. 3

Poison Princess Raffy and Immortal Knight Loren--the very definition of a slow-burn couple. But slow and steady wins the race! So as long as Raffy continues to be the most preciously cute person in existence to Loren, all's well that ends well, right? Wrong. Now that Loren's mentor has accepted their relationship, the next step is obviously to meet the parents. Since Raffy's dad is the Demon Lord, how exactly is an immortal human knight supposed to get approval from mankind's archenemy...?
