What's the ending of the vocal practice of love?

At the company's New Year's Eve party, the kitten got to know Sunsine (played by Ming-hsiang Tung), who has hearing impairment. Unlike A Liang and the ancient capital, although he is physically disabled, his mind is not gloomy at all, but at this time, the kitten no longer believes in love. Sunsine fell in love with the kitten and wanted to be with the kitten, but the kitten told him that love is not that simple, but what is love? After so many years, the kitten didn't understand it very well. Xiaogu found the kitten again, and the giant windmill reappeared as an important scene. When the kitten and A Liang seed of love, they were with Sunsine and Xiaogu, as if the windmill was the witness of the kitten's love road. In the mottled observation deck, the passion of the kitten and Xiao Gu is hard to suppress, and the mottled wall seems to symbolize the scarred heart of the kitten. Who is the most important in her heart, A Liang? Xiao Gu? Or Sunsine? The kitten's attitude towards love is wandering, but she really wants a crystallization of love, that is, a child. The kitten visited Sunsine's home. Sunsine, who was kind, cheerful and sunny, made the kitten feel ashamed. The kitten decided to move away from A Liang's home and avoid Sunsine's pursuit. A Liang decided to stay with the kitten. He said that they are a family, and I want a little happiness in those squares. The kitten pointed to the houses on the other side and said to A Liang, I hope I am your number one family, A Liang replied. I've been thinking about what love is. Maybe love really doesn't have an answer as you said, but maybe it's love that still supports each other after repeated injuries. The kitten left Xiao Gu a short message, and he cried after reading it, because he knew that the kitten really left him. Three months later, Sunsine sent a short message with only eight words to the kitten: They all love you, and so do I.
