Both of the female leads travel back in time to the Qing Dynasty. There, the female leads capture the attention of the princes and get entangled with them.

The male lead has a trust issue with female lead. Female lead was naggy and somehow a troublemaker. Most importantly all the male characters are good looking and would not waste your time if your interests in multiple personalities men. And most importantly I would say that these 2 dramas are short and very straightforward to the point. And finally these 2 drama just gives me the same sentimental mixed emotions and very unique storyline.

Both talk about youth, school, kindness, friendship. Both also talk about a girl not so great in studies, sitting next to a super smart boy who is a top student in the class. Both girls have a crush on the boys sitting next to them.

Both dramas are set in mystical worlds. The relationship between the lead couple are very similar. Both have open endings.

Both dramas are long-episode long dramas about families. Especially "mothers" play an important role, and so does the difference between social classes. In both dramas we have a female lead with a similar background and both yearn for their real family/family member.

Both dramas deal with a bored housewife finding excitement with another man. If affairs are a sensitive theme for you then I would not recommend either of them.

Both have the same vibes as the ML is taking revenge against the people who hurt him in the past and as part of his revenge sleeps with FL's relative.
