Seventeen-year-old Lin Jianwei received a silent confession from Cheng Huaiyan with a kiss in the stairwell of her cousin's wedding - the Cheng family heir who was ten years older than her and as gentle as jade, under the shadow of family marriage, burned all the restrained love and crumbling despair into a tough yet gentle kiss.
In the next ten years, she carried this secret and went north to study, repeatedly tracing the green light on the canvas; he moved step by step in the ups and downs of the business world, and the scar on the inside of his wrist was as silent as the sapphire on his cuff.
It wasn't until she painted the 327th "Stairwell" and until he signed her consent form for surgery that the two souls trapped by responsibility discovered that some love is not for possession, but for letting each other become the wind flying to freedom.
