both Japanese drama with same plot awkward situation of marriage at first then slowly develop or learn to relation/love . the drama shows the initial feeling of love, when butterfly travels in your stomach . and by time going every layered to be revealed of their life with different flavor jealousy, care, obsession's , fear and past experiences with light note.

The overall set up is somewhat similar; both have a romance that arises while the female lead works for the male lead. The cinematography and the writing is also somewhat reminiscent of each other, especially the lines the female lead has.

Both shows have a story line of human evolving into a superior being. In that aspect they are similar but the flow of the story is different.

While Sweet Home has a lot of characters focused in, Ajin centered on one main character only.

Sweet Home and Ajin has different twists but the vibe and enjoyable range are equal. So if you enjoy either of the two, the other one will highly hook you too.

Similar story about romance of a normal person and a deaf girl. In Fukuoka Ren'ai 13, some of the problems faced by the couple in Kimi no Te are even discussed although directly not shown on-screen (because the focus isn't the marriage life).

MRIAG isn't out yet but some of the story seems similar to MGIAG. Only in MGIAG the ML has the females pearl and the FL wants to become human.

It covers part of The Lost Tomb series with The Lost Tomb being first in the series. This season is set after Explore With the Note TLT2.

-Both of the female leads loved a man but was taken by the emperor.
- Both of the male leads worked for the emperor.
- There is a sweet/ bitter sweet ending.
- Both of the female leads helped the emperor in the palace.
-Both of the female leads are smart.

On a personal note both had me raging on certain episodes. There are some lessons you could learn from watching these dramas....
- Don't wait.
-Small decisions can change your life.
-Don't lose yourself.
-Don't put yourself in a position where other people have control over your life.
-You never really know a person.
-You don't always have to put other people before you. (be selfish sometimes)
-The closest people can turn on you in an instant.

both kinda talk about the work environment from a newbies pov. in both they go through alot of tension and struggles trying to understand the dynamics of a not so perfect and suffocating block that one can't easily fit into

Both are fantasy ,romance ,drama that take the parallel aspect well executed;while extraordinary you is school ,parallel love is about business and
the main couple is older .

I have watch the previous seasons. I hope you can still find a way to put back LEE JIN WOOK in the lead role for Season 4. He justified the role very much and it went as very highly anticipated series. He has the very strong appeal to make the series very commendable.
Why not make a twist. You have shown that he died but can you make the story like he only had a near missed shot, a grazed shot in which he survived at the latter part. You just need to show the world that he died and sent him off because he needs to catch the real culprit. Then add the romance together with LEE HA NA to make the viewers more alive. If that would be the ending, it was very sad and I wouldnt want to watch anymore the next season because of Lee Jin Wook and Lee Ha Na. He should still remain as Do Kang Woo to finish as what he started and to be involved seriously with Lee Ha Na. They do have a great chemistry.
I find Song Seung Heon too old or matured for the role. I would still prefer Lee Jin Wook if possible. Please make it possible for Lee Jin Wook.

Both dramas are about a normal world suddenly being swept with a virus that turns humans into monsters. Packed with suspense and horror, if you liked one you'd like the other.

One of the main plot points in 18 again is the dad attending his children's school as a student and helping one of them against bullying. That is exactly the same premise in Angry Mom; a mother finds out her daughter is being bullied at school and ends up enrolling as a student to make sure the other kids stop.

The feel is kinda similar.
Also both are quite dark and has a few deaths in them.
There's a male lead that has some kind of power that makes them special and able to fight against the ...whatever's evil.

Similar vibes on long-term dated exes who meet after years and work together at an architecture company.

I don’t want to be friends with you is much more complex than this lovely us but they both have similar themes — growing up, friendships, family, love stories that last a life time. They are both dramas that leave you feeling warm inside. I don’t want to he friends with you surely makes you cry a lot more tho but don’t worry it ends well <3
