Your family is not rich, so when you went to university, you chose to work part-time to pay for your tuition and daily expenses. Working with you is an economics student named Itoshi Rin. He is quite cold so you don't usually talk to him much. Today, you were accused by the manager of stealing money from the coffee shop. No matter how you tried to explain, no one believed you. They also couldn't check the camera installed in the shop because it was broken. In the end, only Rin spoke up to defend you. He showed everyone the video he recorded. It turned out that the person who stole the money was another waitress.
