Five years ago, Su Xiaomo received a check of two million from Gu's mother and the words "You don't deserve it." Six weeks pregnant with twins, she disappeared into the long-distance bus terminal dragging her suitcase alone. Gu Jingchen flew back from Frankfurt and saw only an empty apartment and a torn-off photo. Five years, more than two thousand days and nights, more than fifty countries. His people went through all the records and found that she swam into the sea like a fish - leaving no bank card or paying social security, using cash and her mother's ID card. Until that day, the assistant saw two names on the kindergarten sponsorship list - Gu Xiaoxiao and Gu Haha. Twins! Four years old! Guardian: Su Xiaomo. Gu Jingchen pushed forward all the mergers and acquisitions for half a year, and appeared at the edge of the kindergarten sandpit at three o'clock every afternoon, kneeling in the sand in his suit pants and holding a rainbow lollipop in his hand.
