Entering to the third grade in junior, his family also feels his study pressure. For the sake of making him involved in study, the family decides to let him live a school. In this way, he can concentrate on study. He deeply appreciates the family's concern to him, but he also understands the school is not peaceful as his families thought.

    It is raining for more than two weeks, which make them feel annoyed. In the meantime water leakage appears in the classroom under the soak of rain. That morning, the English teacher just walked into classroom to have a class, hearing the classmate behind "Ah". Turning around, we see the position of that classmate starts to leak. Quite a few small holes appear in the roof and water is slowly streaming from those small holes.

    After a short while, water on the ground has already more than one basin. To let the teacher have a class as soon as possible, he initiatively demands to sit together with another classmate. So, he listens to the teacher and simultaneously listens to the rain, and enters into a new study environment.
