It was already late at night, and Si Cheng'ao dragged his weary body back home. "There are classes tomorrow; my junior high school sister should have fallen asleep by now," Si Cheng'ao thought: "I'll go check on her. With all the missed classes and working lately, I haven't taken good care of her; she must be mad." But he worked part-time for the sole reason of her birthday coming up in two days - he had to give her a surprise. Since their parents passed away when they were young, even though there was insurance money, the cost of schooling was high. So usually, wherever there was a need for money, it relied on Si Cheng'ao's part-time job earnings. When he entered his sister's room, he found that she was already asleep, but the blanket had completely fallen onto the floor. "Still haven't gotten rid of this bad habit," Si Cheng'ao sighed, preparing to walk forward, pick up the blanket, shake off the dust, and cover it over his sister's body.
