Love Game in Eastern Fantasy and The First Night With the Duke are similar because both of them have fl who time travel

Both have:
- Cold & Unfeeling MLs who are incredibly powerful
- Quirky & playful FLs
- Epic love stories that span across the heaven realm/mortal realm/demon realm

Based on the pilot, the plots of both shows seem similar - the female lead strives for a revenge body after a nasty breakup, with help from the handsome fitness instructor male lead.

~ Fantasy Elements [Demons/Humans/Mages with Powers]
~ Powerful Lead Characters [both have strong Male and Female leads]
~ Slow-burn Romance
~ Strong Themes of Friendship and Family
~ Investigation and Mysteries
~ Great Cinematography and Visuals
~ Great CGI and Fight Scenes
~ Famous and Talented Cast

MLs are very popular , in Road to rebirth he is a huge established star who falls from grace. FLs become assistants and then lovers. ML falls for FL first. Story of RTR more detailed as it is a longer show.

MLs are popular idols who go through a rough patch,especially internally in their careers.
Misunderstandings in both shows lead to FL and ML fake dating though it is more in Smile to Life.
both shows have Famous ML and Common FL trope.

I wouldn't say these two dramas are very similar, but here are some reasons why I'm recommending this:

~ Fantasy Elements [Demons/Humans/Mages with Powers]
~ Powerful Lead Characters [Both have strong male and female leads . the ML in AOS weak at first but evolves]
~ Slow-burn Romance
~ Investigation and Mysteries
~ Strong Themes of Friendship and Family
~ Famous and Talented Cast
~ Great Cinematography and Visuals
~ Great CGI and Fight Scenes

similarities in ML's being popular idols and good looking.
FL s in both work temporarily as assistants to the ML but have their own professions/dreams.

~ Powerful Male Leads
~ Powerful Female Lead (LIP>FOF)
~ Demons-Humans have powers [Fantasy]
~ Investigations
~ Friendship/Family
~ Romance
~ Famous Cast (even for supporting/guest roles) and Excellent Acting!
~ Great CGI and Fight Scenes
~ Cinematography
~ Amazing OSTs

funfact : The FOF ml actor has a cameo in the first episodes of LIP [Neo Hou]

Both dramas have a group of people working together to uncover conspiracies.
In both, one of the lead falls victim to villain's conspiracy. In WCL, ML can transform onto cat while in FYH, FL transforms into another person.
Team dynamic is nice to watch.

(Vague to avoid spoilers)

Both Taiwanese dramas have similar storylines where a mentally stable guy falls in love with a another guy who has a psychological condition caused by a past traumatic event. They both feature the characters trying to navigate the other characters condition and find a path of healing together.

In shark the ML gets revenge on his bully and is sent to prison where he gets mentored to learn how to fight. Both shark and weak hero 2 have the aspects of school fighting with both sharing a crazy villain character

-The first couple Arc and Arms story is somewhat similar to We Are Pheem and Phums story from enemies to lover.
-The second side couple Pond and Sand their story is smooth as butter nothing disturbed their relationship, same goes for the two character played by the same actors in We are. Though there story was unexpected it was shining with a lot of hints.
-The fourth couple or the third main couple Faifa and Wine there story is pretty outgoing in We are these two are similar to Tan and Fang, Faifa with the personality of Tan i think it suits great while Wine with a similar personality calm and caring he suits as Fang.
-As for Yotha and Gun i couldn't find any similar, in We are the other couples i haven't said a word about is Toey and Q There stories are completely different but i still think there maybe a bit of similar stuff for both of these couples. I may have not found them but I'm sure other people who are looking for recommendations can figure the similarities
-Both takes in university (engineering ,Arts stands in the way for these two series)
-Both series takes the lead for comedy
-Both series have a lot of couples ( We are: Phum, Pheem/Toey Q/Fang, Tan/Chain, Pun )

They have the same overall premise, such as-
1. One of the MCs being a suspected killer in a previous cold/unsolved case from a decade or two ago
2. One MC believing that the other is the killer, while struggling to prove it
3. Teaming up between the suspected killer detective and the one that suspects them
4. Old case resurfacing

1. Central Role of the Female Teacher:
In both dramas, a young, idealistic female teacher plays a crucial role in motivating or protecting the students.

She often stands out in a corrupt or apathetic system as someone who genuinely cares about the students' futures.

2. Emotional Anchor and Moral Compass:
These teachers serve as emotional anchors for the male protagonists, often inspiring them to fight—not just physically but also to better themselves or protect others.

They frequently represent hope or a reason to endure hardship in environments filled with violence or deception.

3. Target of Threats or Corruption:
In both shows, the teacher is sometimes a target—either physically threatened or pressured by the corrupt forces within the school.
