(Dare not say I love you) What do you mean in the end?

I just finished watching it. . In order to rescue the imprisoned hero Li Heizi, the heroine Lan Xin promised to donate a kidney to her half-brother. After the hero knew it, he misunderstood that the heroine was leaving. Because he felt that he was not qualified to meet the heroine, he only left a message for the heroine's good friend's mobile phone and asked her to tell Lan Xin. Finally, the hero is preparing to get on the bus and line up in the No.2 carriage. Suddenly I heard on the radio that a lady was waiting for him in car 7. . Then he rushed to car 7. . Theoretically, the lady waiting for him should be the heroine, and they finally came together. . Happy ending.
