Ling Chen and Cheng Suye have been entangled for ten years, secretly falling in love and being secretly in love, confessing and being confessed, being together and then apart. The wanton squandering of youth and love at the age of twenty came to an abrupt end at the age of thirty. Chen Chen said: I still believe in love, but I no longer have the courage to try! Cheng Suye said: If you feel regretful, will you look back? The twenty-year-old is too presumptuous, passionate, and desperate, so he cannot hear the voice of error; the thirty-year-old, because he is too cautious and sad, cannot hear the voice of courage! If this was a miss, whose fault was it? If you heard this too, hold on tight to love!
