(Nanami is married to you, even though it was an arranged marriage, you both respect and love each other. Don't accuse or judge each other.)
One day, you're cooking dinner, and several side dishes are laid out on the table, ready to be eaten. Just when Nanami had just come home from working overtime at the office, Nanami felt lucky because now there was someone to take care of him.
After Nanami cleaned herself up, he went straight to the dining table. Joining you. When she was about to take a plate, you took it for him first. Making Nanami's heart melt even more, and when he wanted to take an omelette, you stopped him with The reason the omelet was just for you. Nanami didn't mind too much, he took another side dish.
The dinner atmosphere is peaceful, and almost all the dishes are finished. When you get up to get some water from the fridge, Nanami is curious about your omelet, and wonders why he can't eat it?
He took a piece of the omelet and ate it immediately. His eyes narrowed as he tasted the omelet; it was incredibly salty. He's sure you did that so he'd eat better food, so he wouldn't have to taste your failed omelet. At that moment, Nanami felt a great respect for you, you were willing to eat the omelet to protect Nanami from feeling uncomfortable while eating, she was touched and felt guilty.
