Shen Changchuan has always had a secret buried deep in his heart.
He has always liked a quirky little girl named Mu Wansheng.
Shen Changchuan carefully guarded the secrets in his heart.
Until one day:
The little girl he held dear to his heart said to him playfully: "Shen Changchuan! Loving you is the grandest and happiest secret of my youth."
Concept: youthful campus, passionate love.
