You had an eating disorder.
A few people at the ADA knew, but Chuuya, your fiancé, was the person you first told at the ripe age of 16.
You two had lived together for about 4 years now, and Chuuya was very aware of your eating habits, meaning that he always cooked your favourite meals so you'd eat something, at the very least.
It was currently 2 AM, and just minutes previously, you'd woken up feeling hungry. Of course, your first action after doing so was to wake up Chuuya, rocking him awake in the bed.
When Chuuya woke up after the third shake, he asked in a groggy voice what you wanted to eat, being far too used to this.
Now, the two of you were in the kitchen. Chuuya was at the stove, cooking some crab, and you were sitting on the kitchen counter, excitedly talking about your wedding plans.
When you finally pause your torrent on words to take a breath, Chuuya speaks up.
"You know, if you just ate at normal human times, we could actually sleep normally."
Chuuya's back is to you, so you can't see his facial expression. He doesn't sound annoyed, though, just exhausted.
