Both are feel-good, slice-of-life high school dramas that make you feel nostalgic with characters you love and want to root for and best friends who clearly like each other but won't admit it.

Both have interesting stories! Both dramas have ghost romance! Both dramas have mystery to find out why they're ghosts and also trying to bring back their memories.

Also a short mini series with short episodes. Very funny due to physical humor and misunderstandings. Although the story and characters are different. The type of humor is very similar.

Same Director Lin Yufen (who also worked on Love O2O and Journey of Flower) both based on C-Novels, Xianxia with a strong romance core.

Both stories have felines play pivotal roles in the main leads progression.

Both center around a man who runs a place in a zone out of the ordinary life (an inn on the desert / midnigth eatery). Despite wuxia disguise, Ashes of Time share similar slice-of-life vibe that Shinya Shokudo is famous for, featuring several smaller stories of different people.

They have the same kind of fluffy feeling in the beginnings and the way Joon Jae has to teach nearly everything about the world to Sim Chim Chung is similar as Louis hardships to get know the world. So in SKL the girl teaches the boy about how to live a normal life and in LOTBS the boy teaches the girl.
One more thing: in Legend of The Blue Sea Joon Jae forgat Shim Chung because she erased his memories. On Shopping King Louis he also forgat everything because he had amnesia.

While Duel is more suspense thriller, and IRY is more crime solving - what stood out for me was the heartbreaking bro-angst of two characters in both dramas. Without spoiling, you'll realise by the end of both dramas, which characters I might be referring to. If you drop either of the dramas too early, you won't find out :(

Hoping for season 3, Season 1 all the actors are new except for some from Love Sick the series but most are only supporting, as for the main cast, Fuse (Peak), Tee (Boom), Fame(Ohm) and Book(Toey) all of them are good especially Fuse and Tee, their love for each other after many setbacks at the end they are together again, same with Fame & Book.
For the story lines season 1 looks more innocence however, season 2 most of them have grown up and are more open in their acting can consider Make it right 1 & 2 is still the best BL series so far.
Some may find season 1 is better than season 2 but we shouldn't compare between series because every season have a different story to tell. anyway seriously hoping if the producer is reading this comments there are many hoping for seasons 3.
Lastly line to the directors (I understand season 2 have a few assistant directors) and producers, staff and all, you have done a great job for giving us this series and for Making it Right!

Both are from the same screenwriter Kaneshiro Kazuki and I both are crime doramas. I got from similat feel from them, but I find BORDER a bit darker in execution. Both are interiting watch with great ending.

- basically the same plot but a remake
- K.O3an Guo is the older version

- aired by the same director
- same genre style: youth, romance, comedy

It’s about a group of students living a normal life and falls in love.

Both dramas have a fantasy aspect. In Chicago Typewriter, the way the drama switches back and forth from present- day to the 1930s is similar to how W switches between the real world and manhwa world.

Both about youth, friendship and rooftops!
Hit the Top is more about achieving dreams (and time travels), while BITFT it's about overcoming hardships.
plus, both starred Kim Min Jae
