It's basic and boring af, plus IF I'm remotely right then it is such a predictable ending.
At the very least, mingwa should explore more of Jaekyung's redeeming arc and of course their relationship, and also for Dan with his new life since you know granny might x-x soon
And if mingwa does it well then maybe (and finally) Jaekyung will acceptable by 0.0001%

Please don't let the plot be him winning the match and then Dan finally done working for him then he retires from boxing, instead focusing with training other people like his mentor
