Both of the plots are based on a "contract marriage" where eventually both of the main characters start to develop romantic feelings for each other.

Both of the main leads in these dramas are in a fake relationship, but they come to love each other.

They both have a similar office setting where the main female actress is working with her ex-boyfriend. Also, these are two short drama series.

Basically, all of the "Itazura na Kiss" movies and TV dramas are very closely similar to "Good Morning Call". The male protagonist is cold and straightforward, the female lead is clumsy, but warm-hearted. The plots are overlapping with the love story between the main two.

Pretty similar office rom-com dramas. They have the overlapping "mean boss" and the awkward but lovable main female lead. Both very enjoyable!

Both of these drama are education and love related in a school/university. Somehow, the whole "being the student on top" thing was quite common in both of these series and showed the ugly side of the Korean education system, how feisty the students can become for good marks.

Both of these dramas mainly focus on the developing romantic relationship between a boss and an employee at his company.

Both dramas are historical, filled with comedy, romance and royal family matters. The female leads in both of these series are very similar in my view, also caught up in a love triangle with two men + the hidden king motif.

Both dramas have a mean cold-hearted lead male character in the beginning. Also, there seems to be a concept similarity in two of the main leads being in the wrong relationships in both "She Was Pretty" and "Itazura na Kiss".

In both dramas the two main male leads (also childhood friends) are fighting over a female in a rich-poor society circumstances.

This is the first movie and it's a must-watch! The beautiful love story and how it started!

Both dramas are circled around an airhead and doctor main heroine and a rich-boy male lead. The marriage aspect seems a bit similar as well.
