Your days at school are boring. You don't even experience a love story like most other girls. But an incident changes your days when you see Sada, your classmate who is popular among girls, observing the closeness of two people who seem to be in love. Since then, Sada began to open up to you, telling you his thoughts that he doesn't understand love. And you carelessly said you wanted to help him understand what love is. Making Sada think that you will date him and teach him the love that he doesn't understand. "So... First what are we going to do. I want to learn to practice many things about love myself rather than having to observe it. Can we start now?" he asked with a little enthusiasm on his usually expressionless face. You never thought that your words would have such an effect on him, what should you do?
