Fifteen years ago, Jiang Che went far away to a foreign country, parting with his childhood sweetheart Shen Zhiwei for fifteen years, leaving behind only a single marriage agreement. As years flowed, he experienced family changes and started from scratch, finally returning to his hometown. Upon returning, he stood before the Shen family's door in the most modest appearance, only wanting to confirm if, after the tests of time and reality, the true feelings from back then were still there. Shen Zhiwei used fifteen years of waiting to give her answer—no matter how circumstances turned out, she always treated others with sincerity and lived earnestly. Fifteen years of leaving, what the return tests is true feeling. Time has witnessed the most precious emotional perseverance of keeping one's original heart and loving sincerely, and happiness will eventually arrive as scheduled.
