The Must-Watch Continuation of Tang San’s Journey
"If you’ve just finished the first part of the Douluo Continent and are wondering where the story goes next, The Land of Warriors (Soul Land 2) is exactly what you’re looking for.
The story picks up exactly where it left off: right after Tang Hao rescues Tang San and Xiao Wu from Bibi Dong at the Spirit Hall tournament. While the series features an entirely different cast, it faithfully follows the next chapter of Tang San’s journey as he begins his intense training under his father.

Night Traveler and Chicago Typewriter share a strikingly similar narrative core, as both dramas use a dual-timeline structure to bridge the modern day with the high-stakes 1930s era of colonial Korea. While Chicago Typewriter uses reincarnation to connect three resistance fighters to their modern counterparts, Night Traveler employs a time-slip mechanic where a modern apartment physically transforms into its 1937 version every night, allowing a modern forensic investigator to meet a principled lawyer from the past. Both series blend fated romance with thriller and mystery elements, as characters in both timelines must uncover long-buried secrets and navigate the political dangers of the past to understand their present-day connection. This combination of period-piece aesthetics, fated bonds across time, and an underlying investigation into fated history makes them spiritual successors in the niche genre of historical-supernatural romance.

Both follow mythical fox creatures (demon or spirit), with concepts of fantasy and fighting all the same. Includes a legendary cast as well, and second-lead couple stories!! One thing to note, fox spirit matchmaker has multiple dramas in the same universe, sort of continuing the story (in way).

Both dramas have morally grey characters, a villainous female lead, a heavy focus on the entertainment industry, and they also both explore how far one would go to achieve their own ambitions/desires.

Though the plots are quite different, the special effects are top tier in both dramas. The monster parade is high-definition, diverse and entertaining. Both dramas also use an innocent-hero type of ML.

AFA is more supernatural and mythology-linked, SH is true horror with a scifi bent.

Seconding the ONHCT rec - these are both Taiwanese dramas with a supernatural story. There are elements of Chinese myths throughout. Both dramas involve reluctant but decisive MLs, who have simple souls but also very strong moral compassess. In both cases, the plot is strong and the special effects are good and support the story.

It looks like if SK has the knack of horror dramas, Taiwan is sure getting ahead when it's about supernatural.

Both shows show a case of an individual loosing their mind living at a Goshiwon (Residency). In Trigger, this only applies to the first criminal case in the show (roughly 2-3 episodes), whilst Strangers from Hell delves into this storyline as a whole.

During this time, both MCs in that case share the same values, emotional outbursts and mental instability. Both MCs have an influencing figure grooming them into commiting criminal acts.

Both shows tackle the subject of preventing or succumbing of these sociopathic tendencies to kill others. Trigger focuses more on the preventing side whilst Strangers of Hell focuses on succuming to that nature. Both shows are quite alike, crime, thriller and psychological. Two sides of the same coin.

Sci-fi comedic mysteries.
Both about female lead being coworkers with an alien.
Hotel business vs kitchen setting.

The core concept of both series involves communication between characters from different points in time. In Kairos, the male protagonist lived three months ahead of the female lead, using a cell phone for their interactions. Time Rescue follows a comparable storyline, but with a time gap of 12 days, utilizing a lantern for their exchanges.

Both FLs are powerful and immortal, MLs are human. Both SMLs have a long time obsessive love for the FL. Both are xianxias with a similar vibe.

Similar with the investigations, addresses sensitive topics, and they are centred around justice for the people who can't get justice for themselves, ghosts and probono cases, they all deal with one case per 2 episodes ish

Mad Concrete Dreams, Dream Life of Mr Kim, Walking on Thin Ice, etc - so many dramas about ordinary people resorting to illegal activities to "win" in the rat race - are just variants on Squid Games season 1. (Seasons 2 and 3 are trash), Season 1 is a "molotov coctail thrown to expose exploitation by elites" as one reviewers so well described it. Imo they are also a molotov coctails thrown to expose how the flaws and dumbness of ordinary people lead them to be pions and exploited by the elites.
So if you want to watch the most violent deep-source, root-causes version of MCD, then watch Squid Games season 1.

Both seem to be adapted from the same script so it follows the same storyline. A down and out heiress in debt hooks up with her cheating fiancé's uncle.

If you're interested in Park Gyu Young in another romantic lead , with a different flavor to Fall in Love, I recommend Dali & the Cocky Prince. Quirky and fresh, her character was softer, with more frills... And you get to see her range.
