Lin Yu's classes were indeed very full on a normal basis, and he barely had any free time because of his research project.
He had gotten used to this because, after all, he never needed much free time before.
But now that Liu Ou was here, Lin Yu felt that this busy lifestyle might not be so good anymore.
However, Liu Ou comforted him saying it didn't matter, since she was also busy starting her internship; as a newcomer, no matter the time or industry, she had the most to learn.
Generally speaking, this process is indeed the most difficult.
There can be a significant psychological gap, as you might find that although you were one of the top students in school, at the new workplace, you feel more like a dogsbody.

But the good thing is, Liu Ou has always been steady and mature in her disposition.
It's not that she doesn't feel any psychological gap, but she can accept it.
