Thank you ! and I will add here my music findings in this drama :
Ep8 - The first song playing softly in the karaoke room where Jiaxu was being introduced to a woman by his colleagues was the first hit song of Mao Buyi 毛不易 : 《消愁》Xiāo chóu ("Drowning sorrows ") which contributed to MBY winning a singing competition in the summer of 2017, where Victor Ma Boqian also took part. Here is a link to its live performance: https://www.youtube.com/watch?v=ZHGN3ViWrns
