Not having emotions and being robotic... Many K-Dramas have the main character starting off soulless (for numerous reasons!). Then they meet someone who changes them and puts in some emotions. Here are some of the K-Dramas with such character developments! 

My Mister (2018)

One of the most popular K-Dramas yet, and for all the right reasons. This drama is about the female lead who had absolutely zero emotions and just went about her days as empty as possible until she got entangled with someone from work. It's not a romantic drama and will surely make you sob, so TISSUES READY!

Starring: IU, Lee Sun Kyun

The smile has left your eyes (2018)

The male lead is soulless because he forgot his past, but the girl he falls in love with helps him not only by picking up his memories from the past but also by putting in the smile that has left his eyes. 

Starring: Seo In Guk, Jung So Min, Park Sung Woong

The One and Only (2021)

The female lead has been through so much ever since she was younger, so her defense mechanism is to remain emotionless. She remained emotionless despite knowing that she has a terminal illness and will die soon. However, after meeting the male lead, along with three other friends she made at hospice care, her world changed.

Starring: Ahn Eun Jin, Kim Kyung Nam, Kang Ye Won, Joy

Just Between Lovers (2017)

The two leads were involved in an accident when they were younger and grew up struggling mentally, and some years later, as if fate brought them together, they crossed paths and help each other face their trauma and overcome their pain.

Starring: Lee Junho, Won Jin Ah, Lee Ki Woo, Kang Hana

My Liberation Notes (2022)

The female lead wants to be liberated from her boring life, where she feels lonely and unfulfilled, while the male lead is always drunk. Watch how they both help change each other's lives. 

Starring: Kim Ji Won, Son Suk Ku, Lee El, Lee Min Ki

Doom At Your Service (2021)

Myul Mang is a messenger between gods and humans. He was born between dark and light, and just by existing, something or even everything can fall into ruin. Living like this, you'd also be pretty depressed and live with no emotions right, But after a 100-day contract with a human, both lives changed. 

Starring: Park Bo Young, Seo In Guk

Something About 1% (2016)

The male lead is a pragmatic and slightly mean chaebol, but he softens and falls in love once he meets the female lead.

Starring: Ha Seokjin, Jeon Somin

Nevertheless (2021)

Not really emotionless, but the male lead was a player and did not want to commit until he fell deeper and deeper for the female lead.

Starring: Song Kang, Han So Hee

Hotel Del Luna (2019)

The female lead is a cursed immortal, seemingly traumatized by her past, cold, and devoid of feelings until she slowly but surely falls for the male lead.

Starring: IU, Yoo Jin Goo

Because This Is My First Life

The male lead is a stickler for rules, odd, and not romantic at all, with no understanding of the dynamics of love and relationships until he moves in with the female lead.

Starring: Lee Min Ki, Jung So Min

Weak hero Class 1 

Before being friends with Sooho, Shi Eun was only very focused on studying and nothing else. The first time we see Shi Eun smile is because of Sooho—a beautiful friendship story.
