This was such an easy and light watch! I had this show on my watchlist for a while without even knowing what it was about and yesterday I decided to go and binge-watch it. It was so good I stayed up until almost 3 am to finish it.

21 Days Theory is a cute fluffy bl with an innocent love story between two highschoolers with the ocasional contribute of their friends and Q's mother and uncle. It's sweet, short and there's nothing particularly groundbreaking about it - but there's also nothing particularly faulty about it which makes for a wonderful easy watch.

The characters are all super lovable. Q is a dorky guy who keeps losing but his will to actually win isn't very strong either - he goes into auditions and competitions already expecting to lose. The reason he has the will to take X up on his challenge is more due to the other's teasing rather than his own will to win. He's also a sweet guy who cares about others, even if he doesn't always show it. X is a rather interesting character, he's super soft and caring on the inside but manages to have this playful and teasing outside that just gets into Q's nerves. Their dynamic is funny and cute, the way they grow closer is also sweet. X is also somewhat cunning, his plan was elaborated and not something anyone would've come up with - tho his plan didn't make much sense (poor guy akdaka), it did work to a certain extent. Q's friends, Toy and Frank are some of the best friends he could have, they're always ready to help him out and are super understanding - there's one specific line in the 3rd episode that made me even fonder of them. X's friend, Mook, the net idol, is also a good friend and she's also a likeable character; she's not full of herself or has an attitude - she's friendly and positive. Mind is also a nice character. The best side character tho, are Q's mother and uncle. Q's uncle is queer and he serves as a support to Q, even if the latter doesn't immediately see him as so admdkaka. Q's mother although hesitant at first is also ready to wholeheartedly support her son. She's also really nice and affectionate with the way she embraces X as well.

The acting was great, especially from the actor who plays X, Bever - he has a great flow to his movements and speech, acting seems natural to him and he definitely stands out. The other actors weren't bad either, Q's actor, Tee, is a cutie.

Production-wise this was way better than I thought it'd be for a low-budget production, the editing is very clean and it's well directed, better than many big budget shows.

Overall, this short series is definitely a gem in the huge repertoire of bls we get nowadays, its fluffy and sweet atmosphere combined with how easy it is to watch will have me coming back to it often in the future. Hoping for more bls like this ><

Thank you for reading and hope you give it a chance!
