They both have the same fl Yang Zi. Both are modern drama that’s really cute. Great chemistry from the leads also heavy on romance. The only difference is that TOOL so far has a better storyline than GGS especially the chemistry and Yang Zi style is so adorable in TOOL. Both dramas the leads are great friends in real life so go watch the behind the scenes to see their amazing friendship! Also bonus TOOL Yang Zi and Xiao Zhan behind the scenes are just as great if not even greater then GGS Yang Zi and Li Xian.

Same female lead Yang Zi who literally has the best acting gig like you seriously will be hooked into her acting.
Both has one of the best plots for its genres.
Devoted leads who really love and care for each other.
No fake badass leads.
After watching both shows it’ll be forever stuck with you like seriously they’re both so amazing!

Basically the same it’s historical/fantasy and Yang zi is the fl that’s naive too. The only differences is that in DOTWS xiao bai realizes her feelings early on, unlike our fl in HSALF where she didn’t realize it for a long time due to the unfeeling pill.
