Both are romance between General Female Lead and Male Lead and have historical background that focuses on war and inheritance of the throne.

Similar concept of demon, demon hunter, and demon vs human with prestigious sects. Plot include mystery added in romance which the fate of the world is in the hand of the leads's decision

Also a lovely BL story without physical lawdness and/or psycho games that many BL dramas will have,
and also has women as positive (and negative lol) part of daily life of anyone in BL - unlike so many BL dramas that make you feel like there are no other kinds of people in the entire world

Similar police drama about a female detective working along with a criminal psychology professor in solving serial murder case.

If you liked Summer Strike, you’ll probably like 18×2: Beyond Youthful Days too, not because they’re that similar, but because they share a similar vibe. Both are slower-paced and focus more on emotions and atmosphere rather than big plot twists. Summer Strike is more calm and healing, while 18×2 is more emotional and can hit pretty hard. If you enjoyed the reflective, quiet tone of Summer Strike, this is a good follow-up, just expect something a bit heavier.

Has you seconding guessing everything! Intense thrilling plot, both characters have a mysterious side to them. If you liked mouse you will def like blind.

Vigilante Justice: Heroes who bypass a broken legal system to punish villains manually.

Elite Combat: Grounded, high-intensity choreography (Boxing in Bloodhounds; MMA/Judo in Vigilante).

The "Small vs. Big" Trope: Disciplined young men taking on massive, corrupt organizations.

Dark Tone: A focus on urban noir, heavy stakes, and bone-crunching realism.

Bloodhounds is a high-speed buddy-cop action piece; Vigilante is a dark psychological thriller.

Based on tags and early promotional material, both dramas share themes of royalty, historical setting, and forbidden BL romance. This is an anticipated similarity prior to release.

Gorgeous cinematography that enhances their bittersweet storylines. These both stray away from the typical fluffy high school romcoms and instead give more suffocating, emotional, and traumatic takes on youth. Whiplash between warmth and cold.

Focus on two female leads who develop a strong friendship.
Both star Ueto Aya and Saitoh Takumi.
Ueto Aya's characters are hesitant to act on their feelings for Saitoh Takumi's characters.

Both are japanese BL about a bit older, moody writer and his new assistant who only came to help because of some favor to pay back but it develops into something more sexual with feelings very quick.

The Novelist / The Pornographer has a lot of parts and some people are confused about the order, so here is how it aired:
1. The Novelist (season 1)
2. Mood Indigo (season 2) (some say to watch this first but it chronologically came after Novelist and contains the backstory of characters that you are not supposed to know yet in Novelist ok? it is mainly a prequel but also has parts that play after Novelist, so it is also a sequel)
3. Spring Life (short movie)
4. The Novelist / Pornographer: Playback (movie)
5. Continued Spring Life (also short movie)
