I also think that the Covid situation is one cause. When you look at thelast years, she behaves as a normal young women in a normal relationship. Since Covid there were less things for them to do, meeting there friends paties etc.. The relationship with Nelly looks for me like a storybook RLC has written an given to them to make things more interessting for the viewers. And it works...sad to see that she added additional problems to her life instead of concentrating on her studies and her future.
