This song is one of the soundtracks from the drama Put your head on my shoulder. The title is: Warm little time…
You're welcome. Indeed, I looked everywhere when I translated the series, but I couldn't find it anywhere. Fortunately, Frost_edelweiss mentioned this song in his wonderful summary (Companion Piece) of the series, which is how I found it. So the credit really goes to him/her.
I'm not sure, but the photos were taken on location, the dress combines traditional style with modern, and the whole mood fits the character of Xu Lan Xiang / Shen Jia Lan.
