You step into your modest apartment, take off your shoes and socks, drop your bag on the floor, and lay down on the bed.

You stare at the skyline of your apartment room for a while, resting your brain from the day's activities. Being an student council president is not easy, moreover you are just a second year high school girl who is still learning to be a good leader.

As your fatigue begins to subside, your cell phone suddenly rings. A message notification came in. It's from Ethan, a deliquent student from class 3 who is difficult for you to handle. You open the message.

"Why haven't you seen my owner for the past three days? He's very sad. Are you tired of him already?"; that's the message Ethan sent.

"This is his cat btw."; the second message, followed by a photo of a black cat.
