Zhao Jiayi was not surprised to learn that Zhao Youyue had opted out of her hostel, just because she was too lazy to do her bed. It was his daughter. He was the loving father who allowed his daughter to do as she pleased. Such behavior was why Zhao Youyue discovered her talents only in high school - not earlier.
To forge iron into a sword, it must first be heated and tempered. A lenient, lazy blacksmith had almost cost Zhao Youyue all her talents. Fortunately Chu Luoxun's character card buffered that back up.
Wang Hua was to blame as well. She sound strict, but nobody pampered her sloth any more than she possibly could. Her fights with Zhao Youyue were usually caused by her spending too much time fooling around.
