(and also Seasons 2 and 3 of this same series); DR follows a highly skilled and reserved doctor with miraculous abilities and a bad temper, and his different students throughout the seasons who grow as doctors and as humans as the episodes progress.
While DR is a hard-core medical drama with very little focus on other developments, it is very similar in its approach to the medical ethics and the patients as side-characters. Both dramas deal with central characters that are doctors and nurses, and who in turn deal with an array of patients with different conditions belonging to their offbeat and remote corner of South Korea.
If you are more inclined towards the medicine side of Doctor on the Edge, DR might be up your ally.

friendly neighbourhood medical shenanigans, a Seoul-based cold and practical doctor, a big-hearted island girl/guy next door, island setting, the doctor who sticks to their morals and proves to be skilled despite being materialistic and grows to love the small town.

Very similar if you're here for:
powerful fantasy world
enemies-to-lovers
fate working against the couple
lots of emotional suffering before the happy payoff

It mainly tells the love story between the witty and cute Cui Xiao Xiao and the sinister and handsome demon Wei Jie in a chaotic time and space zone. Master once said to Cui Xiao Xiao, who has a ten-injury fate, is actually very lucky. If she had been born two hundred years earlier, according to her Yin destiny, she would have become the nemesis of the evil master Wei Jie. If that happens, frail Xiao Xiao will be hunted to the end of the world, her bones broken and ashes raised.

Xiao Xiao secretly calls out: "What a close call. Wei Jie is a cold and cruel person. Fortunately, he was killed by his cowardly disciple Qin Ling Xiao two hundred years ago. There is no such devil in the world anymore! Leaving only his notoriety to last forever. Later, Cui Xiao Xiao accidentally travelled back to two hundred years ago and took a handsome and unruly young man as her apprentice.

Cui Xiao Xiao was very happy and secretly prayed to her Master’s spirit in heaven: Our Lingshan Fu Sect has finally blossomed! I will definitely train my disciples to become talents! After praying, she turned to look at her tall and well-built beloved disciple and asked with a smile: "Disciple, I forgot to ask, what is your surname?" The disciple looked into the master's shining eyes and said slowly: "My surname is Wei, the name is Wei Jie."
