One Smile is Very Alluring (2016) is a good and cute movie version of the novel written by Gu Man. Watch the movie before watching Love O2O (2016), the TV series, that way the movie version will not feel too rush and you will be able to appreciate without making comparisons. Although the movie could’ve been longer to accommodate some needed character development, the characters’ portrayal on this movie has a natural flow and the cast has good chemistry which makes the movie pleasing to watch. Enjoy it, and don’t forget to watch the series!
