Both series give off a similar feeling; main character has a supernatural ability and their close acquaintance is detective/police. There's also a crime mystery surrounding the neighborhood they live in.

The reporters and news team are under pressure to quickly put out stories before the other networks to top the TV ratings game. Reporters struggle to separate the real from the fake stories. Both dramas involve prosecutors as main characters. Both are thrillers.

Both dramas are about the daily life of the reporters in the field and their news room activities. Pinocchio has the idol drama feel and is comedic with romance.

Both focus on a set of roommates during college. Each have characters with distinct personalities, problems they face, and romances. The relationships built between the roommates in Age of Youth feel similar to the ones of Exclusive Memory.
Also, both have some really cute romance!

Both dramas share the same screenwriter as well as a few actors (including Jo Seung Woo as a lead). With Ms. Lee screenwriting, both dramas have a similar feel to them, so if you like the tone of one you’ll probably like the tone of the other. Although one is a crime drama and the other is a medical drama, both involve individuals and institutions pitted against each other. Both dramas also feature male leads who are a bit aloof, as well as a mystery (though the mystery is more prominent in Stranger, whereas in Life other elements are at play).

Very similar with both having a love triangle. However, “wolf girl and black prince” there isn’t cohabitation.

Same plot but “Two loves under one roof” contains a love triangle. It is also a kind of sequel to LDK, so watch that one first!

The plot centers around a rich boy who likes a poor girl and his three other friends. The friends in Rooftop Prince remind me a lot of the F4 in boys over flowers.

Both dramas deal with the publishing industry and how how older women are discovering their true talents in that world

-Both involve guy being in mafia

You will love Gokusen series which is super old but a classic, filled with loads of comedy between a group of youngsters with mismatching personalities but lots of touching memorable moments too. Gotta say Japan does this friendship/comedy/youth genre the best. Watch Gokusen you won't regret it!
