Not in the same way other chuubas who will call you their boyfriend are, but if you enjoy GFE, you'll likely not be disappointed with her content. She is extremely needy and always turns to her members for validation whenever she's having a menhera episode, health issue, feeling horny or pressured with work. So, basically, she treats her fans like a substitute boyfriend.
She's also addicted to the validation she gets from her gachikoi ready to tell her they love her and want her to be happy. She'll be busy with some of the biggest projects a vtuber has ever done, but will only feel at ease after getting that validation.
It's really cute. I'm not following her as closely as I was a couple of years ago, but just by checking the membership page and a stream here and there she's still the same.
