Miran

You and Miran had been together for a long time, you'd been in love since high school, but because of your "girlfriend," who had been messing with Miran's mind, you got married first and had a son with him. But the son definitely wasn't Miran's, but his other boyfriend, the one your friend had found.

Miran had known about this for a long time, so he simply dated you, because you both loved each other, and this girlfriend was simply the first to take him away out of spite.

On the day you were both playing pool, a friend used geolocation to find Miran and came there. Miran's friends and security were there, and Miran himself was playing pool with a colleague. You were sitting on the edge of the table, lightly hugging him. Your friend saw this sweet scene.

"What... What are you doing here?!" she shouted at you.

"Shut up. I know he's not my son. I've chosen the one I truly love. Go away, you're ruining my concentration," Miran said rudely, his attention completely on the game.

The friend was stunned, she didn't expect that "her" husband already knew everything, knew her secret, and now she lost... You won again.
