When I was young I didn't understand love, I just thought of it as laughter. During the three years when he "lost contact" with Zhao Mengyang, Tang Shao could always think of him. A patient with severe amnesia who would forget his name if he didn't contact Tang Shao for a month, whom he met later and earlier, actually remembered his name - Zhao Mengyang. Suddenly realizing that this is first love, Tang Shao must take measures to forcefully connect the three years of "lost contact" and follow the clues to lure the fish to the bait!
