Recommendations

The group dynamics and the comedy aspect with the romance subplot and the addition of the supernatural stuff is very similar imo. The only difference is the seven relics is a bit on the creepier side and if you get scared easily then it MIGHT not be for you.

Rebirth/revenge plot
Scheming, intelligent, morally-grey FLs

SOKP has more toxic/red flag ML, but the two storylines/plot is very similar; if you were a fan of SOKP, you will love Ashes to Crown

* Chen Duling , you outdid yourself with this one !!!!!

Both have a slightly chaotic irreverence combined with a dark suspense, real drama, lovable cast, and oddball thieves you kinda love. Also a unique cinematography style, especially around the ML's point of view.

Both are Thai GLs that involve a character manipulating time to ensure that she can have a future with the woman she loves.

- same director
- two people living together, sharing meals, being perceived as a couple despite not being in a romantic relationship at all
- male lead(s) is/are gay
- important and relevant female character

This recommendation may seem somewhat orthodox, as these movies are really different in plot and genre. However, i still find them pretty sinilar in the sense that to both theres much more than what they seem like in the beginning. Both movies feature a little plot twist so its best to go in uninformed. ((They start off as (fake)documentaries, however [spoiler] also focus on the directors and tell the story of how these documentaries came to be.))

Both dramas center around uncovering hidden truths within a school setting. High Cookie focuses on the mysterious and dangerous allure of a magical cookie that grants desires but comes with a steep price. On the other hand, Teach You a Lesson takes a more grounded, analytical approach, following a specialized team as they resolve complex student issues and restore harmony to challenging school environments.
Compelling Character Dynamics: The character writing in both series is top-tier. Instead of typical high school tropes, you get multi-layered leads who are highly intelligent, calculated, and determined to protect those who matter to most to them.
The Brilliant Kim Mu Yeol: The absolute highlight for fans is seeing actor Kim Mu Yeol shine in both series! He shows incredible range, transforming from the enigmatic, calculative exam consultant Yoo Seong Pil in High Cookie into the highly charismatic, sharp, and commanding field supervisor Na Hwa Jin in Teach You a Lesson. His screen presence alone makes both shows worth watching

School violence and bullying are central themes.

Teach You A Lesson has some clips from the prequel of Study Group 2 at episode 2, 2:33, specifically, the tattooed gangsters.

They also share the same 'Blue String Universe'.

it follows two leads whose relationship is tested by conflicting loyalties, misunderstandings, and difficult choices. as they face hardships together, they uncover hidden truths, challenge long-held prejudices, and grow closer through their shared journey.

ambitious women rises through a ruthless political landscape while their relationship with a powerful ruler develops alongside their shared goals. like many of the stories above, it blends romance with court intrigue, ambition, and the pursuit of power.

it follows two leads who grow through hardship and rely on each other to overcome obstacles. both challenge the circumstances they were born into and work together to build a better future.
