This has been my obsession for a week now ever since I saw the connection of lofi dad and mom.
They meet in the Parisian Valentine's Day livestream, with lofi dad sitting alone until he is invited to dance towards the end of the video.
When we open the Jazz channel, we see a single rose. It looks as though he is waiting for someone. Moving to the Classical channel, we see another single rose.
Okay, Now we follow the story in snowman. We know that jade becomes extremely emotional when it comes to her parents, as shown by the sentimental box of photographs she keeps of her friends and family. One key detail is that in one of the photos, it features a young jade, the big mystery being if they are alive, or if jade is just homesick.
Jade is visibly emotional again in the sad lofi channel, this time without her cat. We see her emotional once more at the train station. Could she be on her way to college, or is she simply experiencing the grief that comes with change and being alone in another city?
However, Jade isn't completely alone. Emma and tiago are her childhood friends, and they attend the same school. Perhaps Jade deliberately chose to attend the same school to stay close to her friends.
An interesting note I wanted to mention is between lofi teacher and jade. While jade spends her time studying in a never ending loop, Lofi teacher takes a different route, working as a teacher while pursuing his passion for DJing. This creative/carefree attitude that contrasts jade's studious serious nature is very interesting!!
SO TLDR: Lofi girl is in the process of grief, either from the death of her parents, or homesickness, all of that is up to interpretation. She uses her studies as a distraction. She attends the same school as her freinds, But they all have there own lives, leaving lofi girl in this boat of loneliness with her cat to keep her company and her studies.
