The cherry blossoms rustled on the sugar-frosted vows on the wishing tree in the old street. At that time, Lin Zhixia always put the burnt biscuits into Jiang Yanzhou's hands and looked at him frowning but chewing seriously. At that time, even the wind was wrapped in pure sweetness. But the rain of fate poured down without warning, and a warehouse fire swallowed up all the good things like an evil spirit - Lin Zhixia's mother tried her best to protect her daughter, but she herself was killed in the sea of fire. Jiang Yanzhou's hands were burned by an accident caused by Xia Xia's father in that disaster. From then on, he was insulated from his beloved piano. He could only wear cold mechanical prostheses and wander around the cold battlefield of the business empire.
Ten years passed, and Jiang Yanzhou's suit and leather shoes were full of scars. Late at night, mechanical fingers unconsciously tapped the unfinished melody of "Sweetness of Summer" on the table. Lin Zhixia traveled across the ocean, trying to fill the hole in his heart with flour and butter in front of the oven of a foreign bakery, but he could never forget the painful look of Jiang Yanzhou when he was burned. The grievances between their parents are like an airtight net, trapping the two in a whirlpool of love and hate. Misunderstandings and resentments grow like wild weeds.
Now we meet again, Jiang Yanzhou's mechanical prosthesis touches the carved copper mold left by Lin Zhixia's mother, the coolness of the metal and the hotness of memories clash at the fingertips; Lin Zhixia looks at his incomplete hands, the past comes flooding back like a tide, and hatred and guilt surge in her heart. On the edge of the cliff of love and pain, how should they break free from the shackles of their fathers' conspiracy? Can the oath separated by hatred and misunderstanding be rejuvenated in regret and redemption? What unexpected ending will this sadomasochism that begins with blood and betrayal lead to?
