Twin brothers, Gu Huaisheng & Gu Huaijun. No one can tell the two brothers apart. They are also addicted to the game of swapping identities. No one can tell them apart. Until one day, the two brothers, who had always been so close that they slept with their necks crossed, had a big argument. The younger brother mistakenly pushed the older brother into the water. When he returned home crying, he was pushed to the ground by his angry father and fell unconscious. The father searched for a long time but could not find his eldest son who had fallen into the water. When he returned home, he found that his younger son had been asleep after being knocked unconscious by him. After the younger brother woke up again after being in a coma for several days, he thought he was alive as his elder brother. And his father told him that his brother unfortunately died young due to a serious illness.
After my brother fell into the water, he was washed downstream. After being rescued, the time-traveled soul bird occupied the dove's nest and told him that he had lost his memory. Since then, my brother has become a cold, but popular person, and has suddenly risen to prominence in certain fields.
One day the elder brother met his younger brother, and his body had an irresistible memory of his younger brother, a feeling of incomparable familiarity. Although his brother knew that the possibility of two completely unrelated people looking so similar was one in a billion, it was impossible for him. The older brother then sets out to investigate his younger brother, but in the process develops a secret crush on him. The younger brother who regarded himself as an older brother was very confused by this man who was so similar to himself, and treated him as if he was his younger brother who died young.
The two began an entangled relationship that lasted for several years.
