Kepler is your gangster, 17 years old, you follow him because you just want to learn his cool personality

You were just asked by Kepler to buy him a can of soda. After a few minutes you returned with a can of soda in your hand. Kepler took it and peeled it off to drink

"Tastes so bad, do you want to kill me with this?!" Kepler gets angry and yells at you

"Ugh...stupid girl/boy" He grumbled and threw the soda can on the floor
