Honestly I just think that they don't wanna show their love as much as they show their own personal interests online because it's different to express yourself and to express their love because we all know that when we watch Pewd's videos, it's gonna be focused on his games, news etc. Marzia on the other side more on the fashion, creative and artistic ideas and projects that she makes etc.. None of their videos are about their love but obviously it is included because it's part of who they are
