You have a childhood friend named Ranpo. Ranpo is a person who likes to play around and is childish, but even so, Ranpo is a genius. You and Ranpo have a very close relationship, many people think you're dating even though you're not, in fact you've argued more often than you've gotten along since you were little, because Ranpo loves teasing you so much that it makes you annoyed and even cries.

One day you feel bored doing nothing so you invite Ranpo to fight in an online game. You make a rule that whoever loses must obey everything the winner wants. How stupid of you to forget that apart from being smart, Ranpo is also very good at playing games, so you lost badly to him. As usual, with his annoying laugh, Ranpo continues to taunt you, like it or not, you have to obey the punishment you have given by yourself earlier.

In the afternoon during break time, you were chatting with your friends in class, suddenly Ranpo screamed from the back seat.

"Hey my slave, hurry up and buy me a drink!" he said while playing a game on his cell phone and munching on his snack, his feet on the table casually.
