A sweet romance with no angst.
They are five years apart. Jiang Zeyu is always afraid of hurting her, while the feelings in his heart grow stronger by the day, making him increasingly vulnerable. He clearly resolves to keep his distance from her, yet finds himself caring about everything in her life. He knows Yan Su is someone special to him, but he doesn't know that she fell in love with him at first sight. Only when Yan Su tests the waters bit by bit does he realize he'd been worrying over nothing.
Yan Su: “Jiang Zeyu, swear that you really love me.”
Jiang Zeyu: “I swear.”
Jiang Zeyu: “Little one, your big brother is serious about loving you.”
Jiang Zeyu: “Susu, you're my only wish.”
Yan Su: “Big brother, let's give it a try and date.”
Jiang Zeyu: “My Susu, you've been wronged.”
Yan Su: “I haven't been wronged.”
Jiang Zeyu: “Will you marry me, little one?”
Yan Su: “I will.”
