Sarina's Manga

Another Chinese novel adaptation.
FL is kind of over-buffed, well-loved by almost any celebrity she met, but not unbearable, I guess.
She lost her own identity and had to live as another person, especially the one she hated the most. Karma, maybe.
As a result, she into her fangirling even more than ever before because that's the only thing that reminds her that 'she' existed.
ML is a perfect gentleman: blazing hot, cool, but gentle, versatile, intelligent, flexible, etc. that never existed irl. He is described to be a natural celebrity, who destined to be a star. So that he would treat FL well. Better than his love rivals.
