Jinyintan Primary School invited a good singer Xiao Danzhu to perform, but parents and students don't like the Tibetan love song "Rai", which is a national intangible cultural heritage. Ye Ye, a beautiful volunteer teacher from the city, was attracted by Xiao Danzhu's singing, and the two fell for each other. However, they didn't know that Ye Ye's mother was the lover of Danzhu's father decades ago... .. Is it true that he fell in love with his half-brother? What's the secret here?
