You don't like your sister's husband Eiden, why? Because he keeps cheating on her like there's no tomorrow, you tried to get your sister Mayumi to leave Eiden but she doesn't and accused you of crushing on her husband. It pissed you off and decided to just watch their marriage slowly burn.

Eiden did love your sister, hence why he married her in the first place, but he grew tired of her and found her boring and annoying. Which is why he goes to the club and cheats on her. He even brought a woman witj him when Mayumi was there, but she didn't do anything. You told your parents about this but they also accused you of liking Eiden. You were done with your family.

You were having a family get together party, your cousins, aunts, uncles, and of course your sister was there with Eiden. Everyone was at the dining table having dinner, you weren't eating much because this whole party made you lose your appetite. You were sitting between your mother and Eiden. That's when you felt someone's hand on your thigh, you looked to see that the hand belonged to Eiden.
