Since it has the same director and some casts from Healer, the feeling of watching 7dq is the same: balanced with mystery, action and awesome drama.... Another top notch chemistry of course with Park Min Young again... Thou the genre is historicals BUT, there's no boring moments and the OST are all beautiful..

this is more comedy, but I would say the romance part is really worth swooning... A one sided love that starts from childhood that he chases her till adulthood... It's more of a noona romance but the Chemistry is a big surprise!.. There's also, action and mystery.. And a great OST's as well... Very fun to watch!..

If you want more thriller (but not ghosts, unfortunately) Healer has it too...

Also balanced with bickering romance... Just check it out... Highly recommended!!

If you want more of Ji Woon, she's great on this drama... She's still a High Schooler here...
Thou she's not the lead, but her role is cute...

If you also like a great awesome romance, HEALER has it too... Also with a hidden identity to protect the one she loves... Great OST's too.... No boring/dragging moments...

Combined with action & comedy...... Just watch it & see for yourself, worth re-watching over and over again... Perfectly done & highly recommended!!..

If you want more of Song Hye Kyo, she's great on this drama, acting wise... She has a great chemistry with Jo In sung, nice cinematography and story as well.... There's also "Full House" with Rain which is another cute rom-com..

If you want some more mystery and thrill, Healer has it too.... Thou it's outside school but, romance is over the roof!!.. Combined with action and comedy..... Great OST's too.... It's enjoyable to watch...

If you like mystery/thriller.... Balanced with a bickering romance and comedy.... The plot is amazing....

Great music as well.. You will enjoy it for sure, if you just focus watching it....

If you like School based dramas, then SKK scandal is one.... There's really lessons to learn... This is just on a historical setting... But the thrill & humor is the same.... You wont even notice that you're watching a historical.... Hilarious comedy as well...

Though Healer doesn't have a personality disorder, but he has to disguise himself to accomplish some missions....
Bickering romance, mystery, thriller & comedy... The music is too die for as well....

If you like thriller, mystery & investigative story, Healer has it too. It's just balanced with comedy, romance & action. I noticed that the (old)... music used in ep1 in Signal was also used in Healer on their flashback scenes....
Music is added to have more thrilling feels....
