Dearly beloved, The big wedding is just around the corner, so it's time to get prepared. Nope, it's not the rehearsal dinner; it's the rehearsal for married life! Princess Mehm is worried about the obvious complications surrounding the relationship between Kazuto and his age-challenged fiancee Valkyrie. So, the blue-lipped beauty has ordered the two to participate in a role-playing sim to see how they handle the day-to-day drudgery of 'til death do us part. Plus, just for kicks, the rest of the gang will be paired up and tested as well. Why? Who knows! Who'll win? Who cares! But you don't want to miss the ride, so pucker up and get ready to kiss the bride!
