Similar genre, this is the story of Emperor ShunZhi (15 March 1638 - 5 February 1661 Qing Dynasty) with Empress Xiao Xian or also known as Lady Dong Xiao Wan, later known as Imperial Consort Donggo.

Similar genre, story about a women's life from a princess to an empress, tragedic, romance, historical, political

Slapstick humour, silly, parody, breaking fourth wall. Both are famous epic comedy parody........................

Both movies are comedy about a boy ESPer/psychic wearing glasses. Both are very similar. Both are based on famous manga................

Almost Same period (Forbidden City), very similar clothes but (Legend of Concubine Zhen Huan) seems to have more acurrate sets of clothes and everything.

Similar History!

Same female teacher and younger male student. While chugakusei nikki is more melodramatic, biscuit teacher and star candy is more funny.

Same female teacher and male younger studant dynamic. They fall in love, the girl end everything with their fiancé but people and familly around them are against their relationship.

Has a similar feeling. It's kind of like if you combine the emotions and relationships for Pete/Ae and Tin/Can into one couple you'd get Ai No Kotodama

Lakorns. Mafia/gangsters. Romance. In "Karn La Krang Neung…Nai Hua Jai" main male lead is much more subtle, much more romantic. In "Le Jun Kai" main male lead uses physical and psychical violence towards main female lead.

In both dramas, there is a character who wears bag/box over their face. What else do we want?! This is either because appearance/ identity, etc. They both also have school romance.

Both deliver:
+ Perfect chemistry
+ Hilarious rom-com
+ Adorkable side couple
+ Fashionable styling
+ And not to forget the side bromance

Hit the Top and Shopping King Louie aren't similar in plot, but rather, their lighthearted atmosphere. They both keep you laughing and there's an innocence and light nature to both dramas that simply reminded me of the other drama.

Both dramas have the same actress. It is set in the 1930s. Something bad happens to the girl in the both second last episodes and its in their wedding day, (I'm not revealing what happens).
Both have sexy male leads, I wanna eat them up...(yummmm)
The 2nd female lead seems bad but she's actually good. Full of drama.
The second make lead is evil.

Although TSHLYE is less dramatic and intense compared to Liar Game, they have similar tones of mystery where nothing is as it seems. TSHLYE has a bigger focus on romance and melodrama-type plot twists, but there is a sense that things are not as they seem and highly convoluted plot-lines exist in both dramas. (This includes comparisons to the original Japanese version of Liar Game.)

Both dramas feature rich boys and one poor girl who attends school on a scholarship. Both are over the top comedies with the main hero being a "prince" character and the heroine being blunt and not interested in him at first.
