Damn mirin`
Can you even fix symmetry in abs (in this guys case)? It looks more genetic related.
His left side looks either too relaxed, injured, or disproportionate. Impossible to tell from one image, and that would decide the case. He seems to carry more abdominal fat than other fat -- pretty normal for a dude, but fixable especially if it's just that he didn't contract that side

If it's genetic then there's no real work-around outside of tightening up his abs in general to conceal the difference a bit (or possibly surgery).
