Experiment and safety

Y/n pov
I woke up and seen Deva passed out next to me and her hair covered her face. I kissed her forehead softly and got out of bed quietly. I walked over to the door and snuck out softly closing the door behind me. I had my clothes on and went to find a Library or Kitchen to find something to do. I seen one of the maids and I walked over and tapped her on the shoulder. She looked at me and I bowed softly to her and I stood straight up and I said "Miss do you know where the kitchen or Library is. She gave me instructions to both places and I nodded. The castles library was far closer but I felt like cooking something for everyone or at least Deva and her parents. I made my way to the kitchen and seen maids and butlers there. I knocked at the doorway and they looked at me and one of the butlers came over and asked what I needed. I said "I'm sorry to Interrupt but may I ask what the royal family usually eats early in the morning? The butler asked "before I answer may I ask why you're wondering Mr.
L/n?" I responded "I'm wondering because I want to cook for the royal family today. I am far in their debt and...it looks like you're Understaffed currently." He walked over to the others and talked as a group. The head butler said "you can help but only for today for if the king catches you helping us we could lose our jobs. I bowed and said "Certainly sir I understand but I'll make sure you won't lose your jobs and that's a promise." He nodded and I took a spare Chef's outfit and put it on and he started giving me orders which I followed to completion and I added a couple spices and things that weren't in the recipe. The butlers stared at me with confusion. I started putting trays on carts and I remembered how to cook due to my old family teaching me. The head butler came over to me and asked what was I doing. I said "If you must know sir. When I was in the overworld I was actually a master chef for I have famous cooks in my family. If you don't believe me try my food. After the buffet was served I heard Deva shouting my name. I walked out and I whistled  and said "I'm right here honey." She seen me and ran over to me and asked what was I doing with a stern tone. I handed my Chef's outfit to one of the servants and I turned back to her and said "I'm sorry for sneaking off honey I was looking for the kitchen so I can help Cook breakfast for you guys." I'm already in your guys debt and plus I wanted to surprise you with this. I handed her a cookie cake. She looked at me and her eyes softened and she handed the cookie cake to a maid and asked her to put it in her room. She nodded and took off. I honestly was a bit hurt by her not even taking a taste of it. She seen my hurt expression and I took a seat on the stairs and so she took a seat next to me and tear rolled out of my right eye because I worked nonstop on it for the last 2 hours in the kitchen on it. I quickly wiped the tear because my father said that makes men weak. My face went stotic as I hid my pain as best as I possibly could. She asked "what's bothering you?" I feigned a smile and said "It's nothing honey I'm gonna go walk to the park. I'll catch you later." I got up and walked out of the castle and through the streets to find somewhere to think. I walked out of the capital and found a cliff with a dead tree with a great view of the sea of fire.

Deva pov
I seen Y/n walk out with a smile on his face which I felt someone tap my shoulder and take a seat next to me. I heard my mother say "hey dear I seen Y/n walk out. I could tell he was bothered by something...did you two get into an argument?" I shrugged and my mom sigh and she said "I know why Y/n is upset right now dear." I asked her why he was upset. She pulled out a tablet and it showed Y/n cooking in there and he said "I hope Deva appreciates the desert I made her." I watched the footage of him working his hardest in the kitchen cooking breakfast and dessert. I asked my mom why she was showing me this. My mom said "your Future Husband spent all morning making all of us food and a special dessert for you and I bet when he seen you just give it to our maid to take it to your room that hit him extremely hard because he just worked all morning making food for all of us. He looked...Betrayed when you did that. His whole family were famous cooks and he made something for you and just threw it away. Y/n is extremely sweet and kind to everyone. Our breakfast was far better than how the cooks did it. Your father wanted to make him your personal cook because of how good the food was. We both know how stubborn your dad is to change." What my mother said hit me like a train because I wasn't appreciative of Y/n's surprise. I asked mom where he was and she said "he went to release some pent up anger on the over world. I think you should go find him and apologize to him. I nodded and got up and got dressed to go find Y/n.
