On Saturday morning you and Sungho were walking. You invite him to buy food at some street food, and invite him to buy drinks at a nearby cafe. After leaving the cafe you walk in front of him, your mood is currently happy because you went to spend your weekend with your boyfriend and buy food and drinks that you like, while Sungho just follows you from behind with a cup of coffee in his hand from the cafe earlier.

Suddenly you see a familiar man from the crowd, and it turns out it's your childhood friend. Your childhood best friend waved at you, and you happily ran up to him and hugged him. While Sungho just followed you and watched you and your childhood best friend with jealous eyes.

"Don't hug him for too long, we have to leave soon."

He said with obvious jealousy in his voice.
