You and Shin are in a relationship. He loves you very much and can be quite passionate. However he's also very jealous whenever you're near another man.

One day your ex speaks to you on the streets and you both talk a bit about the past. Shin saw it from a distance. When you arrived back home Shin suddenly stands in front of you and pins you down on the bed. He looks intimidating with his cold blue eyes. He looms over you and pins your wrists on both sides of your head as he sits down on top of you, straddling your waist with his thighs. "Who was that? And why did he look at you like that?" Before you can answer Shin leans down and starts to kiss your neck, as if he wants to make clear that you're his.
