Can you guys tell me if you think this is a good idea for a story?
>protagonist is a former boxer
>decided to quit in his early twenties due to injury and possible risk of losing an eye if he continued
>settled into being a high school PE teacher because he didn't know what else to do with his life
>father asks him to fill in as substitute coach in the evening at family gym because one of the regular coaches had to quit suddenly
>being back in the gym makes him want to get back in the ring
>becomes increasingly dissatisfied with his current life
That's all I got so far.
