The storyline is superb especially after the heart-wrenching ending of One and Only!!
I have read the translated novel of this adaptation prior to watching the series. While the main story plot stayed true to the original novel, there are tidbits of change in the series here and there which I'm actually appreciating as it gave the story a lot more sense.
Not the typical love that suddenly burns hot since the beginning, but the type that start with a spark of fire and continue to get bigger and stronger. Such a romantic and heartwarming love story, where ZSC&SY's love is gradually built up over time. The small love gestures appearing now and then suits the leads' low-key characters. It's really cute every time when ZSC carries SY's purse, although I personally don't usually like it when a guy carries the girl's bags, but somehow when ZSC does it, it just looks freaking adorable! Allen Ren and Bai Lu perfectly act the roles of ZSC&SY, especially the additions of a bit cheekiness to the acts make the couple more lovable than what I imagined when reading the novel.
Although it can be a good standalone series to watch, but I highly recommend to watch One and Only first so that you can feel much deeper emotions while watching Forever and Ever.
