Who should wash their hands?

I was listening to the King kaka and Scar song and remembered this one time we dated the same girl with my friend. She did not know we knew each other.

She watches anime and we do too so we thought we hit a jackpot. She was also slim thick and with a gothic look to her. The tattoos did not scare me or give red flags but I've learnt to touch them with a pinch of ink. She was bad in short.

When I told my friend he realised she was cheating on him. I liked her but he did more for her. So he was invested. My friend is the lover boy type. In comparison I'm the Joey of Friends.

I left her to him. But what should happen to the girl ideally when y'all find out she's cheating with your best friend.

Ps. They are still together and we hangout the three of us 😭
