The Si family is at the top of wealth, but inside it is as cold as an ice cellar. Si Nanyu, an orthodox young master, lives in loneliness where no one cares about him. His kindness and expectation only earn him endless neglect and material compensation from his family. On the day of his coming-of-age ceremony, he waited until late at night in the cold wind, only to be beaten and embarrassed, becoming the most lonely existence on this prosperous island.
Si Mo, the adopted son of the old man of the Si family, is the leader of the overseas underground force "Rusty Blade". He is cold, ascetic, ruthless and paranoid, and is a sharp blade that goes beyond the rules. He was entrusted by the old man to return to the country, and he was supposed to be taking care of him as ordered, but the moment he saw the young man curled up on the balcony blowing out the fire, his heart was stabbed.
He broke into Si Nanyu's closed world silently, healed his wounds after the fight with silent care, blocked all malice for him with a tough stance, and shattered his layers of defenses with paranoid tenderness. Si Nanyu resisted, fled, and pretended to be indifferent, fearing that the short-term warmth would be followed by deeper abandonment, but with his company day after day, he gradually took off all his armor.
From being forced to live together to testing his heart, from being blocked by his family to making a firm choice, the love-starved Lone Island meets the paranoid Rusty Blade, and a two-way redemption begins. Si Mo is the only light in Si Nanyu's dark life, pulling him out of the abyss of loneliness; Si Nanyu is Si Mo's weakness in the cold world, giving the sharp blade the tenderness he wants to protect.
There is no grand romance, only a long-lasting love; there is no false politeness, only staying together until death. When the lonely island finds a harbor, when the rusty blade protects the glimmer of light, the two broken souls heal each other, and finally embrace each other's eternity in the barren years.
Purpose: The true redemption is to use paranoid tenderness to fill the lost love of the original family; when broken souls meet, they can also be each other's armor, turning the barren years into eternity.
