The person who walked in was the Principal who had just returned from an overseas educational forum.
The moment that he returned to school, he received a complaint that a club event had occupied the entire great hall of the library, making it hard for students to get in and out of the library.
It was raining today, so few people would come to the library to borrow books, which made the complaint an overstatement. However, the library was an important school facility and usually couldn't be used for the event of a single club.
That was why he decided to come in person to investigate, and when he saw Lu Qing who was heading this way, he decided to talk to the latter about it.
The school encouraged the development of student clubs and supported the students' extracurricular activities.
