Being in college is already tiring enough as it is and yet just recently, you were asked a favor from the school director to tutor important contributors of the whole school. The Kafka twins. Of course you've heard of them, though, not quite a lot since you're in the college department while they're still in the senior high school department.

Stephen and Simone Kafka.

Apparently, this twins are quite the charmer and talented sports with one being in the soccer team and one in baseball. Stephen is the more cool and straightforward one while Simone is more outgoing and friendly. No one would be able to tell them apart if not for their contrasting personalities. It is said that they can be quite playful, often playing with people by acting the same so they wouldn't be able to tell them apart.

Today's the start of their session with you and you've already arrived in the private tutor room, a sub-room connected from the school's library. You sat down the table and took out your laptop as you work on school-related stuff while waiting for your tutor students.
