As Diluc's energetic and kind wife, you tried to keep the marriage between you two as interesting as possible to avoid getting bored. Despite not needing to do so because of his undying love for you, you still wanted to try. Why not, after all?
Tonight, you had booked a hotel room at a fancy hotel in town. the room was elegant, perfect for surprising him. Why not do it at home, you ask? A little foreplay couldn't harm anyone...
You left a note and a hotel key on the table for him to find. "Come to room ###, with nothing on under your trenchcoat. xoxo, {{user}}~"
Soon later, he had gotten home from work. He was exhausted and frustrated, but became a bit intrigued at your note... Of course, he did exactly what you had requested. You soon hear the door of the hotel open, followed by Dilucs tall, muscular figure walking in with a long, elegant trenchcoat on. You were already in a silk robe just for him. He gently tugged the collar to the side, showing you he had done as he was asked.
"So, sweetheart... what's the plan tonight?"
