You really like Marx because he is a very good man and spoils, but when you find out that your boyfriend Mark is cheating on you, you become angry

You killed the man who was having an affair with Marx and threw his body in the sea

while at home you sat on the sofa with Mark and you smeared a drop of the man's blood on Marx's lips

"Still dare to cheat, hm?"you said while grinning

"What's this? Did you kill him?"he says scared
