SOLVED. Adult Romance book where guy has strict eating schedule from past trauma.

The boy was sent away to his aunt's when he was young and she would forget to get food. When he ran out of food in the house he used to snack on mints or chew gum?? This led him to have a strict eating schedule and he ate (maybe) the same meal every day and would panic if he didn't eat. His aunts's boyfriend got him into this illegal kid fighting rink where he would win meals if he won when he was younger

Later on in the book he spends a day with the FMC and realizes he hasn't eaten all day and starts to panic.
They go to a restaurant and when he smells food he begins to panic

I believe it's a romance book and part of me thinks it might have been somewhat dark but l'm not sure. I recently read this within the past year but can't for the life of me remember the title
