You Make Me Dance (2021)

Both are LGBT dramas with heavy reference to the Red Thread myth of fate (I honestly wish more dramas had plots with this)
Apart from the obvious difference that YMMD is a kdrama and UWMA is a Thai drama, YMMD is kinda lighthearted and short, while UWMA starts with a dark undertone (don't worry, it gets fluffy later) and is longer.
Besides that, UWMA is a must watch for BL fans - I can't help but gush over it!

they are definitely siblings shows. They both are korean bls, similar atmosphere, character dynamics and similar trope. One of the character is really poor for exemple and our topics are sport, romance, challenges

If you like BL dramas, Color Rush is a very well done Korean BL drama that has a very interesting concept from other BL dramas

The young protagonists in these two drama have dream of becoming a dancer on stage. They both have talent stem from their mothers who were once dance in ballet professionally. The young men also have difficulty pursuing their dream due to finances. Also, both young men encounter elderly who helped them achieve the goal.
