Both dramas are set in the same time period and with a lot of the same actors. Barbara is an amazing lead actress in both and she just brings this sassy aura to her characters that make both dramas so interesting.

They gave me similar feelings. Although Mondai no.. is a lot more in depth with issues around social construct, they're both about women that aren't afraid to stand for their beliefs and move on with their lives.

The Story is quite similar, she causes his fiance's death, he wants to get revenge, he tries destroying her life, fell in love with her at the end.

Both are revenge themed dramas, Physical abuse, falling in love to the lady and struggling between revenge and love

If you like drama Signal, there's a huge probability that you will love drama this drama! :D

if you like drama Signal, there's a huge probability that you will love drama Tunnel.

From the same PD and writer. It also discusses similar topic such as social hierarchy and reform.

i talk about school,romance,and handsome boys.It really talk about life and how it goes through and why.

I've been jumping around (skipping scenes in) Princess Agents a lot so sorry if this is completely a completely off recommendation..
but some of the character personalities are very similar.

XE is like QingSuo- others controlling their life, losing memory of their past, stuck in love triangle, stuck with someone who they kinda hate but end up loving

Yu WenYue similar to Yu WenYong (yeah even their names are similar)- royalty, cold on the outside and warm on the inside, always mistaken by their love

Both don't have chaebols, both have mukbang and most importantly characters you can relate to.

Both dramas are of supernatural genre, connecting two time -present and past - to solve cases, revealing missing connections between different ppl. Both dramas have badass female leads. Worth watching. Fighting.

Both dramas are set in 1980's and revolve around high school students and how are their lives affected by political situation of the country. Both main female characters are very similar to each other and overall both dramas have similar feeling.

I highly recommend both!

both are about high school 'power dynamics' with handsome boys as main characters and plenty of bromance.

Legendary Lackey is just a short fun special while School 2013 is more complex story with more serious side.

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..

Both are historical dramas.
The leads have been through so much.
The love between them reminds me of both dramas
