Beside of both talking about high-school students and their relationships and friendships, I find a parallelism between two characters: Win (Hormones) and Tee (Grean Fictions).

They both hurt their crushes' feelings unintentionally, what made them carry a guilty feeling through all the series (Hormones, in Season 2 concretely) and film. That blame is a heavy weight for them and caused their character development.

Both films have a family focus and call out the different treatment daughters receive compared to sons. They also mention a few other female struggles but go about it a little different. Other than that the movies arent similar in tone or story, but i think are both worth a watch.

I have been looking for a as good as Tharntype for ages but none came near. However I finally found it. This show is as good as Tharntype. The acting, the chemistry, the fact that the couple is in a relationship throughout the series instead of all the angst other shows put us through to get the couple together, this show is just incredible.

Both lakorns deal with the male leads wanting revenge against the female leads for causing a car accident with their loved ones. While Sathit's fiance passes away in Kleun Cheewit, the male lead's sister in Ubat Rai Ubat Rak becomes handicapped. Coincidentally, the supporting actor (Masu) who plays Jett in Kleun Cheewit also happens to be the male lead in Ubat Rai Ubat Rak.

Bunch of good friends i their last year of high school.
Preparing for Gaokao.
You'll laugh and you'll cry.
Motivational

10/10 worth the watch.

Both the leads have special power/ extensive knowledge.
Both keep low profile.
The narrative style and feel is very similar.

Killer and Healer shares the same vibes as The Untamed. It is about 2 lonely souls who are polar opposites at the beginning but will become soulmates and will fight together for what it’s right.
Like for the Untamed, there is no doubt about the nature of the relationship and the profound feelings Yue Lou and Yu Zhi have for each other in Killer and Healer. Their love for each other is even more real, sweet and natural in Killer and Healer! Highly recommended!

Another nice BL drama in high school life that follows several gay relationships with familial implications.
And also, there are two twins male actors in the secondary roles.

Both dramas are Korean and base is about Gumiho. Also each episode has a mystery and the leads help or find out. Its really good to watch. I found it randomly on Youtube.
Enjoy!!

basically same thing goes for s2. please, just watch the first two seasons before you watch the third season. i personally liked s2 better than s1, and the smaller duration of eps is better too so you won't get bored as easily. thank you and goodbye

... i recommend you watch this before you watch s3 just for context... it's basically the first season of the series, and if you watch this before s3 you'll understand the characters' more and the plot will make more sense to you than watching s3 before s1

ML is boss of FL
Leads know each other from childhood but only the male leads remember that

ML with psychological issue
FL works for ML who is rich
FL is sweet ,outgoing while ML isnt
FL helps ML in healing process

Both stories are about a 30-something woman wooed by a much younger man and she is torn between adventure and depenadble ML choices.

Both are crime / thriller dramas involved in tracking serial killers, have plenty of twists and turns.
Both have cops/investigators that are involved more or less personally with their cases.
