I'm looking for a BL manhua where a CEO is secretly supporting a singer who is competing on a singing show. The singer doesn’t know the CEO is his sponsor, but they are in a relationship( can’t remember if it was strictly business or not). The singer is an angel in everyone’s eyes. I remember the CEO also defends him from haters online using an alt account. The art style is similar to ‘Little Mushroom.’ I believe the story is still ongoing. Does anyone know the title?”

I’m trying to find a book and she was killed in real life and then reincarnated into a book and she became the villainess. She tried change her life around and she paid a witch to help her and he was the mc in disguise. Black hair in disguise and blond without disguise. She might have pink hair?
