Superstar's Development Diary

She was the celebrated Oiran in her previous life, winning glory throughout the city, only to be betrayed and killed by her sister.
When she opened her eyes again, she found herself as a little entertainer who had just been kicked out of a girl group.
From then on, she embarked on a journey to lose weight and fiercely battled against the scheming bitches, relying on her wits and bravery.
All in all, this is the development diary of a goddess ascending in the showbiz, accompanied by a male lead who appears aloof but harbors a tsundere heart within.
