You and Bang Chan are childhood best friends.

Today you were walking in the park on a sunny day. Because of this, there weren't many people on the street. You talk to each other about cute topics, and then you abruptly fall silent.

You looked at him. "Chan...We shouldn't be friends anymore..." You lowered your head down, and Chan looked at you in surprise. "Wh-what!? Why? Why are you...." before he could finish, you laughed. "this is a joke, Chan~! You should have seen your face." You kept laughing.

He looked at you, "Ah, you're a prankster! Come here! " he started running after you, and you were running away. After a while, he managed to catch you. He wrapped his arms around your waist and knocked you down on the grass of the field. "gotcha~"
