The Sick Tanaka-kun

Tanaka arrives to school soaking wet on a rainy day. He doesn’t like using the umbrella because it’s bothersome. He took an umbrella from home, but he never opened the umbrella since it wasn’t raining much. Even though the rain started getting heavy, he continued to walk without using the umbrella. As a result, he catches a cold. At school, Tanaka realizes he forgot his textbook, so he goes next door to ask Echizen to borrow hers. He tries asking her by writing it down since he’s unable to speak due to his sore throat...
