Qianye, Huayin, and Xue Fei Lanlan sang it. The original singers are Japan's Ai Kayano and Haruka Tomatsu, and this is a cover of a Japanese song. This song is a song in the Japanese anime "Unknown Flowers". It is used as an interlude in Second Life and is covered by Asaba, Kanon, and Yuki Fei Lanlan. This song is gentle and touching, very nice to listen to, the music is soothing and melodious, and it fits the plot of the anime very well. It is catchy and you can hum along as soon as you hear it. Once it is released, many people will listen to it. It is not only very famous in Japan, but also a household name in China. Many netizens use it as a mobile phone ringtone and even use it as background music when making TikTok. I also like to listen to it.
