Thai Boys Love dramas with a high school setting.
Unexpected romance
coming of age
Teenage characters being played by actual teenagers

GMMTV produced high school BL
light hearted, sweet, fluffy, comfort shows
KenPaul play side characters

They are very similar in the sense that
- both FLs are working as a prosecutor/ government based lawyer
- both MLs have done shameful things in the past and have been involved in violence
- the MLs are essentially hiding in some way or the other their other life
- both the couples have a sort of refreshing and natural romance vibe. Like you feel comforted just watching them together
- both MLs save the FL in some way or the other without her knowing
- both have happy endings

Although their tone differs, OSL is a rom-com first and the mafia elements are used as a plot point, while it is almost opposite in Undercover which is a thriller first and romance second.

Similarities: Max cringe, super fun. Both series feature a young man stepping into a fantasy world without any prior knowledge to it and being forced to live with a stranger that they develop feelings for.

Differences: Knot is an Omegaverse and My Golden Blood is a vampire series. Knot is very smutty/nsfw and MGB toes the line between PG-13 and MA18+.

Kinda while watching this movie remembered Friend Zone movie. Overall idea is same friends seek love, but dont see each other.

Thai Boys Love dramas produced by GMMTV and directed by "New" Siwaj with a high school setting.
Both shows are each respective pairing's second work after staring together in Boys in Love.

Main character, who is actually an adult with some regrets, find himself transported back to when he was a teenager/teenage age.
Good Boy > BL
55:15 has an lgbtq+ subplot but follows multiple main characters navigating culture shocks

Well,
1. BL series
2. Author (one novel and the other is screenplay)
3. Age gap

I don’t know what else to write but both are pretty much romance comedy with various flavor (I believe if BOTW has more episodes they could make the plot more convincing and easier to understand)

Both are recent thai boys love dramas with a bit of an unusual setting (or at least no school/uni/work/completely modern day setting like most BL).
Both star Ongsa a main role, so if you liked him in either one of these shows, you may also want to check out more of his works

- Princess FL
- Similar political plot of a ruthless FL fighting all her siblings for the throne
- Cold, domineering FL
- Dom FL x Sub ML

Main difference is the leads' relationship which was enemies to lovers in YBJX with a reluctant ML and devoted master/servant in GZJS,YWRRYXFS with an eager ML.

From same novel writer, exploring world, strong ML and FL, mortal ML and Immortal FL, advanture, diffrent storing in one series

The Road to Splendor and The Prisoner of Beauty share a striking resemblance primarily because they are crafted by the exact same creative duo, director Deng Ke and screenwriter Nan Zhen, which gives both dramas an identical cinematic tone, grand visual style, and fast-paced narrative rhythm. Beyond production design, the two series perfectly mirror each other in character dynamics and tropes; both showcase a highly intelligent, strategic heroine who refuses to be a damsel in distress, paired with a rough, gray-shaded male lead—a battle-hardened general in one and a street-smart salt smuggler in the other. Ultimately, both stories thrive on high-stakes, forced survival alliances that beautifully develop into intense, 'us-against-the-world' power-couple romances."

Fake family compromised of semi/former criminals and a down on her luck woman form for a specific goal and a good pay day.
Over arching conspiracy plot point.
Found family/slight romance progression.
