I originally watched this drama for the actor zhou yiran due to his role in Falling into your smile (haha), but after watching it, I adore this show so much. The filtering and overall concept give a very nostalgic and specific vibe to the entire show. The music is the absolutely best; it fits really well with the scenery and emotions of the characters. Su Zai Zai in the show is SO SO SWEET; I was hesitant about liking her character during the first few episodes, but her overall personality and actions won me over as the episodes progressed. Final line: sweet, engaging, and a must-watch!
