Mysterious Twins

In this short scene, a student asks for more time to pay back the loan he took from the school. The loan shark tells him that he can change the terms of the loan at any time. He also tells the student that the interest rate is very low and that the loan is for one year. The student asks if he can borrow some more money, but the loan shark warns him that there is no benefit to lending money to someone who does not need it. He then tells the students that there are two transfer students in the class and that they are studying so much that they need to borrow some chalk from him. He tells them that he is the older brother of one of the students and the younger sister of the other student. The older brother borrows money from the younger brother to buy chalk. The younger sister borrows the money from her older brother and gives it to the teacher.
