Shi Yeon is a Nine-Tailed Fox living undercover in the human world. By day, Shi Yeon is an employee at a natural history museum. By night, she's a top-ranking woman warrior in the Nine-Tailed Fox clan, charged with preserving the delicate balance between man and fox. But her world is sent spinning when an atrocious serial murder - where the victims have had their internal organs gouged out - is uncovered. Detective Min Woo believes the murders may relate to the organ trafficking trade, and goes undercover in a seedy organ smuggling ring. But Min Woo's cover is blown, and it's only through the intervention Nine-Tailed Fox warriors, Mu Young and Shi Yeon that he's able to survive! But he's seen their true identities as Nine-Tailed Foxes, can he be allowed to live?

Even tho only 1 ep of Our youth came out at this date (9/11/24), I think they are pretty similar since we follow the story of them ( the main leads) through time and years. they are also two bl and follow high schooler that grow up closer due to different reason as time pass.(Idk if Im clear but I hope that you understand)
Sorry for my English.

Both dramas feature an ML with a condition that makes it difficult for him to feel.
In both dramas the ML has to navigate falling for the FL.

Both has very similar story especially the Male lead role is exactly similar where he helps all the village people with their problem. Moreover Female leads in both the dramas quit their job and came to the countryside

similar vibes in both dramas (idk even the soundtrack gave me similar vibes)-
sick male leads in both
exes reunited and have a hate-to-love relationship

Same Director
same abandonment issues
ML leaving the other without explenation
Same rural setting in the winter

Uma semelhança entre "Jun Ru Yu" e "Love's Rebellion" é que ambas as protagonistas enfrentam desafios significativos e se arriscam em diversas situações para garantir a segurança e o bem-estar de seus amados. Elas demonstram uma força emocional e uma determinação inabalável, mostrando que o amor verdadeiro pode levar a sacrifícios profundos e ações corajosas diante das adversidades. Essa disposição em lutar e proteger aqueles que amam é um elemento central nas duas narrativas, evidenciando a profundidade do amor que sentem.

Both leads are raised as siblings, ML loved FL from long ago but is a little mean to her.
...................................................

Both main actors are played by the same wonderful actress if you enjoyed her acting you would surely like her in this role it has LGBT elements

For obvious reasons I made the comparison---both including a character which has been diagnosed with a disease. Although, a warning, very different endings/resolution to this problem.

If you are looking for a drama which involves exes, this is the one as both dramas have exes reunite with one another.

Both are Korean BLs with an office setting and manager-employee relationship and similar personalities between the couples.

Both are office BL romances, with an opposites attract couple.
...................................................

Both are mini dramas in which one of the leads approached the other to take some object, but ended up genuinely falling in love. Both FLs were pregnant when they left and ML has a son he doesn't know exists. Both FLs have amnesia when they reunite with the ML.

Both have the same director so the same style. Both have demons/monsters forming relationships with humans and tragedy.
