In a first-year high school magic theory class, Mo Fan was kicked out of the classroom for questioning the teacher's teaching methods. Shen Yan happened to be late leaving because she was tidying up experimental equipment and bumped into Mo Fan squatting in the corner of the corridor eating bread. A bottle of warm milk that Shen Yan handed over became the starting point for their interaction (Mo Fan stubbornly said, "Who wants to drink this sweet stuff?", but secretly put the milk into his schoolbag).
