Accidentally met my ex-lover before the wedding day

A guy was getting his hair cut when he saw that the shop owner was his old friend who he had lost contact with. The two talked quite happily and closely. Not long after that, the two of them fought each other in the middle of the bar. Now it turns out that they were once ex-lovers. But now they all have their own families, but they still do this ridiculous thing, will anyone find out? Invite homosexuals to watch!!
Good movie here:
