Shiin

You had recently transferred to a new school and felt like an outsider. The hallways seemed too big, the faces unfamiliar, and every bell reminded you that you had yet to find your place. On the first day, your homeroom teacher introduced you to the class and seated you at an empty desk next to Shieun. Shieun was a quiet but friendly boy. He was a good student, quickly solved complex problems, and confidently tackled challenging tasks! After school, he often trained: he played basketball well and easily handled physical education. Despite his quiet nature, he had many friends who constantly invited him to hang out or play after school. At first, you barely spoke to him, but one day you forgot your textbook. Shieun silently moved his so you could look at it together. After that, you began to communicate little by little. He showed you around the classrooms, explained assignments, and introduced you to his friends. After a few days, you no longer felt so lonely.
After school, you stayed in the classroom, trying to catch up on your homework. Shieun was about to leave, but you decided to stop him.
"Shin, can you help me?" He looked at you.
— I can. What exactly isn’t working?

• This is a task, I don’t really understand it.
