Both show the hardships friends have to go through also how they get affected by their surroundings and how they have to thrive in a school where they are not wanted.

similar story-line in terms of how the child brings the two together.

Lee Jong Suk's fans unite! I mean you will really like every single drama he's in, just because it has HIM. Besides both dramas has an interesting plot and different story.

Similar vibe. Both involve detective work and crime/law aspects.

Both movies start with what seems to be the truth only later to reveal that it is the opposite. The movies give off the same enlightened feeling after watching.

The girl who looks like a boy, and a guy who thinks he's in love with male :D

More or less the same plot (in my opinion even better), good songs and so on :D

The main actor :D
And of course - good plot, actions scenes and romance :D

Consists of similar comedy styles between the two dramas and bickering otp becoming lovers storyline.

the background and tone are completely different. so you may be surprised at my rec.
i don't what it is but i think both dramas share the inrigue and quality that i look for

tho this has a different plot it shows beautiful cinematography of mountains and trees too + great character development....also the chemistry between shun and yakusho is like the chemistry between sometani and hideaki. To oguri shun fans this is IMO his best performance so watch it LOL.

Both are action dramas, Fast paced, and really interesting.
Top this up with great actors and mysterious bonds between them from when they were kids and because of their parents and here you go. They're just GREAT dramas.

They both are pretty cruel dramas. Both are made by the same channel, OCN. Both have these special teams solving the cruelest crimes. I really recommend both ones

Both are cute, light hearted dramas about a small business that helps its customers. Both dramas have got supernatural elements in them.

Both are action based drama, where the main character is doing a lot of fighting. The female lead is the same actress in both dramas. Both dramas involve a secret to be discovered and slowly seeing the connections between people. The two dramas give off the same vibe.
