On a very pleasant morning, Tanaka is taking a nap in the school courtyard. His classmate, Ohta, carries him to class, but Tanaka continues to sleep on his desk. Tanaka’s listlessness is nothing new to his classmates, so no one is surprised. But, the usually lazy Tanaka is willing to participate in PE. His goal is to train his body and prevent his limbs from going numb or injuring himself from being lazy all day. He teams up with Ohta to play badminton...

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...

Today is Valentine’s Day. While girls and boys are excited, Tanaka, who’s not interested in Valentine’s at all, finds a box of chocolates inside his bag. Judging by the pretty box, it’s obvious the giver has feelings for him, but Tanaka feels despair just thinking about having to show gratitude or giving something in return. There’s no name on the attached message and only says “I’m watching you all the time.” Tanaka and Ohta try to figure out the culprit... i.e. the girl behind the chocolates.

To Tanaka, nothing is more important than having a peaceful life. He’ll spare no effort to be lazy and will try everything he can to secure the optimum location during the seating change. Attracted to Tanaka, Shiraishi hopes to be closer to him since she got to seat right next to him.
