Heart to Heart (2015)

Both deal with mental illness and are very good at showing the spectrum of the human condition. In both dramas one of the characters is a psychiastrist and also in both dramas both characters suffer different mental illnesses.

Both females have a physical insecurity and the male lead is there to help them heal by being their coach/doctor. And who falls in love with them, insecurities and all.

... from the same writer. Both of them have unique atmosphere and characters.

Both female leads suffer from social phobia. There are many scenes in Heart to Heart that are very similar to the scenes from Castaway on the Moon (the helmet and umbrella ones), the director probably got inspired by the movie.

The shows are similar in the aspect that the female lead has psychological problems and the male lead is helping her through (tough) love. At the same time the male lead also receives healing through the female lead.

The female lead on both movie were introverted. Social phobia. Stay to self. Poverty. Live with an older lady. Romace were cute and heartwarming

ML is an actor but not too popular anymore & broke so he rent a room in FL house.
FL is a nerdy geeky/otaku girl who like to imagine & day dreaming about romance with her favorite manga/comic book character. Remind me of Rainie Yang & Jiro Wang drama....& still 1 of my favorite drama....If you like this genre this is a must watch romance comedy drama....

The male lead were introverted, social phobia, discovered by the male lead. Society cruelty. Learning social skill. Stepping out of comfort zone, romance,

Not very similar
Except
for the part that female lead blushes uncontrollably
Male leads are handsome

Both shows have two guys literally fighting over the female lead and perusing her from the start to the end in a fun way. The male leads in both shows are massive jerks, but you forgive them in the end. However, I enjoyed the Jealousy incarnate much more.

The stories are vastly different but I couldn't help but notice similarities between both dramas.
Similarities:
-The main female leads look and dress alike.
-The female leads are curious about the world but also shy (Heart to Heart's character has an actual social phobia and is WAY worse)
-The female leads knit and have a cleaning obsession.
-The romance between the male and female lead is VERY unusual and the people around them are always trying to break things off. (For the sake of the female lead)
Differences:
- Plot: Heart to Heart centers around a woman who has severe social phobia and slowly develops a relationship with her psychiatrist. Mary Stayed Out All Night is about a girl who's desperately trying to get out of an arrange marriage and gets into a fake marriage with a stranger she hits with her car...
- Romance:The psychiatrist falls and chases after the female lead first in Heart to Heart but Mary Stayed Out All Night is the other way around.
-Heart To Heart centers around the psychiatrist's job and the people they meet along the way whereas Mary Stayed Out All Night is focused on music and whether the female lead will escape the arrange marriage or not.
Both shows have a lot of charm to them and is great for a rainy day!!

Both stories about a psychologist falling in love however Heart to Heart it is his patient and Madame Antoine it is a fortune teller
however they both share the common themes of love as well as psychology also some quirky moments and lite comedy.

both dramas tell of a love story involving an introverted heroine who has hidden herself away after a scarring experience, and an extroverted fast speaking (and cute) hero, who helps her step out her doorstep and into the world waiting for her outside.

Love the second leads in both of these dramas. It is for different reasons but both of the leading ladies have a ruddy unattractive appearance. Both dramas follow the usual Rom/Com formula (leading man is successful and handsome/leading lady is hardworking and has a good heart). In both dramas the leading man is drawn to the leading lady due to his own insecurities/fears.

Both deal with a couple struggling with mental illness and trauma. It’s about how each of them helps the other heal and overcome their individual trauma.
The main characters in both dramas are also quite eccentric and interesting in their own way.
Overall, the dramas have the same vibe, if you enjoyed one you will most likely enjoy the other!
