Classic drama about a school bully who falls in love with an innocent girl. Both dramas are old and full of emotions.

It is a romance drama and one of the main themes is a social responsibility of journalists. FL is also a jurnalist.

The male lead is a sexy and cool fire fighter who at the begining does not understand FL intentions.

The begining of the drama has some similar elements. It starts in Italy. ML in both dramas is handsome and cold and speaks Italian. They both want to use FL for their own gain and they both have the same lighter :P

Both dramas depict a forbidden romance between the man serving the monarch and a woman who is a love interest of this monarch (king or emperor).
Both dramas have a fair amount of comedy and a flowerboy ML.

Both dramas are extremaly cliche and cute. ML is rich CEO who creates a fake relationship because of relative wish (grandmother and grandfather). Even the appearance of the actors is similar. FLs also have some shared traits as they pretand to be someone else.

Both dramas are very similar. Main characters are women whe start as a slaves and than climb up to the highest position. Both female leads are entagled with two men and have sons. Both have to endure heavy storms in their lives and fight with intigues and enemies. Both are strong and cunning but in the same time they care for lives of citizens. And they both live in the foreign country in the end. Not to mentione serious and tragic vibe of both dramas.

Both dramas tell a story about a girl dressed as a eunuch and her romance with a handsome king. Both are historical romantic comedies.

Both short series are about a couple of friends who are afraid to become lovers. Both couples start to live together and it shakes balance of their relationship. In my opinion Soundtrack#1 is strongly inspired by You drive me crazy.

Both dramas were made in Japan and have similar vibes. Both take place in special high school for snobs. In both normal girls encounter handsome boys in nice uniforms.

Both dramas takes story in fictional Korea where royal family was restored (or never dethroned). Both dramas focus on love story and responibilities and dificulties that come with the corwn.

General mood of both dramas is smillar. Both are about ML that seem to be tough but find a soft spot for MLs. MLs characters are also smillar.
