But the hard-hearted and pitiless CEO of Alpha Modeling Studio who discovered Mikako is far from a knight in shining armor. Now, "The Goddess Who Never Smiles" is an exclusive top model for a renowned fashion designer. There is no denying: Mikako Asou is successful. So, why on earth would she give it all up so suddenly? "I Want to Protect You": Sawako Shouda may have seen tragedy in her life, but no way is she a damsel in distress. She has her heart and mind set for the future and won't be distracted by anything, not even a frail looking classmate with a face of an angel but words of a snake who asks to be her friend.
