She is a close friend of my classmate “Sun Myung”. Even though she is friendly with Sun Myung, she has a big fault which makes Sun Myung feel embarrassed. To illustrate, she earns 2 million won a month. However, she has never spent money. For instance, when they meet at any place, she is always late not to pay money. Moreover, she intentionally leaves the place very early. Her behavior always lets my classmate feel irritated.
