Gu Siyuan and Lin Xiaoran were childhood sweethearts who grew up wearing crotchless pants. He was a cold and ascetic construction boss in the eyes of outsiders, but he had doted on her for twenty years. Even when drinking milk tea, he remembered to use less sugar and ice. But after the college entrance examination, he suddenly went abroad and cut off all contact, leaving only one sentence: "We are not from the same world." Five years later, Lin Xiaoran returned to China with her own interior design studio. As soon as she received her first order, Party A's father turned out to be Gu Siyuan! The man was in a suit and leather tie, with deep eyes: "Designer Lin, if we can work together, get back together with me first." Lin Xiaoran rolled his eyes and threw out the design drawing: "Mr. Gu, let's talk about work, don't talk about personal affairs - but your office design is so ugly that it hurts my eyes." She turned around and became popular in the industry with her stunning design, but Gu Siyuan was chasing after her, helping her to fend off strange customers while secretly repairing the misunderstanding from the past. Until he took out the engagement ring that he had hidden for five years, and said with red eyes: "Ran Ran, I left without saying goodbye because I was afraid that family grudges would implicate you. Now that I'm back, I will never let go of your hand." Lin Xiaoran raised his eyebrows: "Want to get back together? First, you can waive the rent of my studio for three years, and then you can be my exclusive model and be available at your call."
