Recommendations

Both dramas tell the story of four close friends and what it means to live through love, family, success, and failure. I definitely enjoy and would rather watch female empowerment, but GD also had strong male characters and stories.

Both drama are about divorcees ending up with each other. One More Happy Ending has a ton of divorced characters, but in Emergency Couple, I believe it was just the main couple.

I want to avoid sharing too much, so I'll say this:
if you've already seen one, searching for something similar, watch the other

btw, good shows, based off good novels, some good music, not for sweet dreams..

(I think especially if you've found *yourself* in one, you'll like the other)

regardless of the story, the actors found themselves in characters that fit them perfectly; and are good
(Kamiki Ryunosuke, Katori Shingo, Yamapi / the - incidentally all somewhat anti-heroic - Shizukui Kei, Hiratsuka Heihachi, Saionji Kosuke)
and it's pretty much what holds the shows...

Dragon Zakura is a good kyoushi (bengoshi? ww) dorama and MNO!! is an annoying kyoushi dorama;
the thing I am basing this recommendation off is actually vaguely unrelated to any meaningful part of the shows' composition..: the kids' style
Osakaish GALish kinda bad thing; idk, it brightens me up

this rec might be a bit off the hook, but when I watched the first ep of Shut Up! Flower Boy Band, when I saw first two episodes of Gakkou Kaidan, I felt rock'n'roll ... that's it

The stories are different, but they give out the same vibe. They're both light-hearted and in both you have a delusional ''dorama in the dorama.'' The main character in both is also kind of the ''narrator'' of the stories, and doesn't get involved in the action personally, but acts as a catalyst for the plot.

it's not that they're that similar - completely different you may say, but there's a similarity (hard to grasp similarity that I personally feel in there) and if I said what I think that is, it'd be spoilers ... that kind of thing
somehow, I'm sorry, but I still recommend each to go after the other
..especially if you've seen neither

The female lead triumphs thru difficult trials with the help of the lead actor to attain success. The lead actress are the same.

Story of youth trying to find their way and making the most of events. Has a similar light and "inspiring" vibe. Cha Sik and Junggu have similar personalities (or similar aura).

Stories of youth struggling and making their dreams come true. Also, one character doing what others think is impossible and being the ultimate changing factor in their lives.

Both films are set in an all boys high school, where all the boys are sex obsessed and slightly perverted. An attractive female teacher joins the school and its seen as a sex icon for the guys. Both have a student falling for a teacher.
Wet Dreams is about a group of guys learning about sex; expect crude humour, bad jokes and lots of innuendos. But it is quite funny (bad to the point of being good).
Who Slept With Her is about a female teacher who acts super sexually and its misunderstood to have slept with a student. Again, expect bad jokes, perverted boys and innuendos. Still had funny parts though.
