It's Okay to Not Be Okay (2020)

Here's My Plan has a similar tough and assertive FL . You don't always approve of the FL's actions in either show but you slowly understand why they are the way they are and keep everyone at a distance. Similar dynamics, but Here's My Plan has more slice of life vibes while IOTNBO has more fantasy/melo vibes.

The story begins with Shuji, a high school student in Hokkaido, walking up to an observatory and reminiscing about his girlfriend, Chise. He finds her exchange diaries that she purposefully left behind. The whole story is narrated by him through flashbacks while reading Chise's diary. Chise, a fellow student in his class, declares her love for Shuji at the beginning of the series. However, Chise is very shy and Shuji is insensitive. Neither know how to express their feelings very well, but they do indeed have feelings for each other. One day, while Shuji is shopping in Sapporo, unknown bombers attack the city in broad daylight. He and his friends run for cover, but notice a fast and small flying object shoot down enemy bombers. Separated from his friends, Shuji wanders through the wreckage only to stumble upon Chise. She has metal wings and weapons apparently grafted onto her body. She tells him she has become the ultimate weapon, without her knowledge or consent.

The leads have intense chemistry
Emotional rollercoaster
complicated relationship between the leads
Dark vibes
Sad and traumatic backstory for the leads
Crime element
instead of the FL chasing after the guy, the ML goes after the FL, similar in that its kind of obsessive

It both hero and heroine meet first at their childhood where the heroine is left with the impression that she saves the hero's life (justifieble or not).

Mommy!! This lineup is super expected!! The fork in the road of life has two different lives
"#I live elsewhere#" Zhong Chuxi Liu Xueyi
Plot:
Xia Guo (played by Zhong Chuxi) is an ordinary white-collar gold woman, and her childhood sweetheart boyfriend Yuan Yujian (played by Liu Xueyi) lives an ordinary and happy life in her hometown of Leshan.

The two Xia Guo have experienced different love, friendship, family and workplace, and have gained different growth and happiness

both Another Way and It's Okay to Not Be Okay had hurt and traumatized leads that in some way relied on each other though in Another Way the mains barely interacted.
also both have Seo Ye Ji

- both have a theme/storyline around healing, healing, healing
- definite tearjerker
- also centers around family relationships (very complicated family relationships) and friendships
- plotwists!
- romance
- overall both stories that you wish you could watch for the first time again!

Both are considered healing dramas as the main character struggles to get over their past and regrets through their blooming love for each other and matured.

Similar in these aspects:

- Both have that otherworldly feel to it
- Mystical-like storytelling element
- Dark and based on fairy tales
- Intimidating and powerful female leads
- Hidden past

similar dynamic , the 2 main leads both have something wrong with them and they work together to get better and heal each other along the way

- both are healing dramas.
- the chemistry of the leads are on point.
- both dramas take place in a hospital (in iontbo a psychic hospital and in chococlate a hospice).
- the dramas take place by the sea.

Both feature female protagonists who are blessed with everything, including a great body, smarts, ability to sympathize with others, patience, ability to react quickly, and stamina.

there's no age gap in IOTNBO but in both dramas:
- the FL is rich (and has a great wardrobe) + has been sheltered (personalities differ though)
- FL pursues ML first and relentlessly chases after him
- has a ML who has things holding him back from starting a relationship with FL (in TFF its age gap and his responsibility as an adult, in IOTNBO its his responsibilities and her personality).
- both have great chemistry between leads
other than that plot varies wildly, but I think it's a good rec to keep in mind if you run out of directly similar ones.

Both have a mentally challenge child at home. Fully functioning, smart and genius in someway but mentally struggle in another way. Both have a very committed family member unconditional love

Both dramas are psychological rom-com and the main theme is mostly related to female leads. Both dramas have wonderful leads and a nice romance.
