As others have said, she was living in Japan trying to make it in the underground rap scene, but then the pandemic happened and pretty much ended most of those peoples' music careers. At the same time a friend talked her into auditioning for a vtuber agency and hit it pretty big as a result. So while so many other artists that she knew were forced to go back to regular jobs, her music career took off, and some of them didn't take that very well. And a part of her feels guilty that she found success when others that she looked up to and considered better than her didn't find. So she has the part of the song where she wonders about 'what if' she didn't make it, and all the friends that she would still have; followed by her basically scolding herself for feeling bad or missing the old days, that she isn't allowed to be sad about having found success (which, really she's being too hard on herself, success is rarely achieved without loss, and we're allowed to mourn those losses no matter what we achieve).
