Teoria do Amor (2019)

Both are about a school film-making club and one of the leads having a crush on the other. Both dramas are quite short, one more so than the other.

Both dramas feature one lead who has been in love with the other for years, but after taking a certain amount of abuse from the him, have decided to give up on their love and move on. It is at this point that the other lead realizes their own love and tries to win them back.

Both series have a happy ever after ending that may make viewers wondering if the ML deserves it.

The same main charcters????
Same chemistry( just from seeing the trailer)
Also, outside the movie, there's just amazing chemistry and cuteness between them

Both shows focus on multiple characters and couples, one of the couples going from friends to lovers. The characters are also related to movies (in ToL the characters are filmology majors and in YOUniverse two of the characters collect movie and drama soundtracks). Both dramas also were (co-)directed by the same person, look so so good and have very nice bgm

In both dramas, the main characters work in filmmaking. Also the ML from ToL makes a cameo appearance as that character in episode 5 of VV.

If you liked Off and Gun, then check out their series "Theory Of Love" with the same cast.
Gun plays "Third" and Off plays "Khai" :)

If you miss a fantastic interaction between Off and Gun, than you may love this series. It's not a BL but OffGuns are so OffGuns there

They both are university dramas and both dramas have love triangle so I find the genre similar ofc story is different

Thai BL dramas! one of the couples from Top Secret Together shares a similar story to the main couple in Theory of Love. Best friends, one falls for the other, he rejects him and makes him suffer and then realizes he actually loves him and fights to get his love back when it was already too late!

In Theory of Love, there is a pile of movie references, among them, Dear Dakanda. TOL's first episode name is because of this film.

On the other hand, both productions tell a story about secret unrequiment love for a close friend in a college ambient.

Both series have main characters who start of as friends (with one liking the other as more) and evolving into uncertainty once the second friend realizes that they too like their friend as something more. This inevitably leads to the back and forth doubt and attempt to win his friend over.

Both have MLs who have a crush on their friend who dates a ton of girls in school but never gets serious with any of them.

Similar trope of unexpectedly falling in love. Both have a star couple with great chemistry as main focus. Also a really amazing well made stories.

Both series have very similar plot lines between the main characters. Love to hate to inevitable destined love and learning what it means to love. Theory of Love would be PG-13 where as History: Obsessed gets a solid R rating. Both are entertaining with the Theory of Love being more of a RomCom where History:Obssesed is a full on drama.

Similar themes of young adult love, school, exploration, relationship drama and coming of age.
University students in similar situations.
