Similar vibes but Dear My Room is more focus on the female protagonist than in the romantic plot.
Also, the male protagonists are a bit similar, perhaps due to the long eyelashes eheh

Both leads have professional careers that we see a lot of.
Ml's older sister has a main arc in both dramas.
I feel like You Are My Hero is New Horizon's older sibling... YAMH is way more interesting but has the same feel.
You Are My Hero's romantic progression and plot strength is superior.

I guess as the FL happens to get in a love in this one you would also be able to find not in a love square but I don't know how to put but with four guys and its pretty light and entertaining.

Ep 2 has the feel of 1000 stars feel, plot changes a little. In Hometown's Embrace a teacher from Bangkok came to Isaan to teach, with low pay who will want, however in ATOTS, it was Tian trying to fulfil the wishes of dead Torfun whom donated her heart to Tian, and encountered Phupha along the way. In Hometown's Embrace, we see Mek falls in love with the director's son. However there seems to have a love rival challenging their love.

- living together in the same house (tho not with main guy)

- girl is "poor" but with a secret identity

- main guy is ceo of a company, typical secretary/ceo story

- feel-good cinemtography and sort of slice-of-life city vibes

- business company scheming

- multiple couples

Older woman younger man falls in love. The best Noona-Dongseng love story out there. Both dramas have disapproving mothers. Both dramas have the "slow burn" effect. In both dramas, the man is enthusiastic about love while the woman holds back.

Problems of the work place, sadness, hoe small moments bring us a lot joy is beautifully shown in both the dramas.

BL dramas. Golden Blood (Thailand) HIStory 3:Trapped (Taiwan). In both one of the leads is a son of the Mafia and faces constant dangers, gets involved with the other lead (bodyguard/police officer) and they must face their enemies together while falling in love in the process.

Thai BL dramas. Both include mafia/crime themes and plenty of action scenes. One of the leads is in constant danger while the other has to protect him, eventually they fall in love (both include side couples as well)

Although these dramas have different plots, I feel like they give off a similar vibe. There are harems, politics, and elaborate costumes.

Extracurricular and influence genre is suspense. The conflict involve teenager.

Light on series: the bad kids and influence have same genre about suspense,

Pretty similar in the way both depict an established gay relationship which was born during the innocent high-school years, creating a strong bond between the male leaders. However, when they turn young adults and face new life phases, fears and insecurities come up.

I find both have a similar kind of ending and the same message of personal growth and its relation with relationships.

Not that similar but some similar instances I saw with Raeng Pradtanaha and Praomook is that (SPOILER ALERT)
:1.) Both female leads have an arranged marriage with the male lead
2.)Both female lead's try to take revenge on the male leads by some sort of seduction game
3.)both male lead's hate the female lead at the start.
4.)Both are slow-burn romances.
5.)Both male leads are prone to getting jealous.
6.)Both have married couple problems and it might go as far as to divorcing.
7.)Both Female Lead's haven't succeeded in their plans to get the male lead's to fall in love with them (but Praomook might, not finished airing yet)
8.)Both Male Lead's have an ex girlfriend who tries to screw up the main couples relationship.
9.)Both are childhood friends/acquaintances of some sort.
(In Raeng pradtanaha, the male lead has been in love with the female lead from the start of the drama, in Praomook the viewers feel like the male lead has loved the female lead from the start but it isn't never revealed or not revealed yet...)
(In Praomook though the female leads gets jealous more than the male lead and in Raeng Pradtanaha the male lead gets more jealous often than the female lead)

I recommend this series because the main lead is also smart.. too smart.. both focusing on communist-nationalist conflicts. there's no romance in here but brotherhood relationship. Just wanna request subbers please make an English sub for this one it is a beautiful story
