After school, you have to clean the class, the school is starting to get dark now, you are in a hurry to clean this class.

when you finished, you saw Shizuku waiting for you in front of the class, she just smiled.. When you approached her, she hit you with an object.. and it hurt a lot.. you fainted.. when you woke up you were tied to a chair , you also saw Shizuku smiling, seeing you wake up. "I'm so glad you're awake,... Sorry, did I hit you too hard~?"
