Original: 멈추고 싶은 순간: 어바웃타임
A musical actress with a supernatural time-sensing ability meets a mysterious director who halts her life's countdown, challenging her to pursue her dreams.
Mi Ka is a musical actress trying to get her big break. She has a special skill that allows her to see the remaining time that people have left on their lives. She knows that she only has 167 days left of her life and intends to make the most of it. She meets Do Ha in a car accident and ends up meeting him again in Hainan. Is their meeting a coincidence or is it destiny?
Mi Ka finds it strange why her clock stops when she is with Do Ha. She wishes to stay near him so that she can find out why, but he keeps distance from her. When Mi Ka finds out that Do Ha is holding an audition for a musical, she decides to use that as her opportunity.
Mi Ka gets a job as Do Ha’s driver. She is happy because as long as she’s near him, her clock will stop. Do Ha is confused over the feelings he has for Mi Ka. He asks her to work late and have a meal and watch a movie with him. Meanwhile, Mi Ka wonders where Do Ha’s clock is. She sneaks into the swimming to pool to find it.
Mi Ka tells Do Ha that she does not feel the same when he tells her the he likes her. However, she can’t stop thinking about his confession. Just like Mi Ka, Do Ha can’t stop thinking about what he said to her. He replays the moment in his mind and even calls Seong Bin for a consultation. Meanwhile, Do Ha’s brother, Do San, comes back to Korea.
Mi Ka tells Do Ha that she has been using him to prolong her life. Do Ha tells her that the reason she’s by his side doesn’t matter to him and gives her a kiss. Mi Ka brings Do Ha into the emergency room to help him understand what she means when she says she can see the time left in people’s lives. After speaking with Mi Ka, Do Ha decides that he must end things with Su Bong.
It turns out that So Nyeo is able to see the clocks just as Mi Ka does. Su Bong plans to convince Zhang Qi Yang to cancel the contract so that she can put pressure on Do Ha. Her intention is to interfere with Mi Ka and Do Ha’s relationship so that they can’t go any further. Do Ha figures out Su Bong’s plans and prepares a hidden card to move Qi Yang.
Joo Na’s return to Korea causes Mi Ka’s remaining time to start counting down. Joo Na is to star in the upcoming play. Mi Ka is amazed at Joo Na’s performance and slightly feels intimidated by her and her appearance on Broadway. Meanwhile, Do San is haunted again by his illness that only Mi Ka knows about.
Unable to keep her promise, Mi Ka tells Do Ha about his brother Do San’s illness and the short time he has left to live. To his dismay, he does not believe in Mi Ka's words but soon finds out the truth by going through Do San's medical records. Meanwhile, Do San asks his father, who is reluctant to any of Do San’s request, for money but only receives animosity in return.
Mi Ka realizes that the time she was gaining from being with Do Ha was actually his time. Frightened and worried, she tells Do Ha she will spend the week with her mother but stays at her friend Seong Hee's house. Meanwhile, Su Bong decides to pursue her destiny with Do Ha.
Su Bong has brunch with Mi Ka and Joo Na to tell them she will accept Do Ha’s marriage proposal. Joo Na resigns her position as the lead actress with only a few months left before the first show. Meanwhile, Do Ha does not accept Mi Ka’s unexpected farewell and pursues her for answers.
Mi Ka tells Do Ha the reason for breaking up with him; however, Do Ha still does not give up his love for her and continues to search for a way to be with her.
Director Cho faces an onslaught of pressure from Do Ha and the members of the play to quickly find a replacement for Joo Na. But, his stubbornness to do things he desires puts him out of a job. The tension heightens as Do Ha refuses to give into Su Bong’s marriage plans that causes her to take to extreme measures affecting all those around him. Meanwhile, Do Ha still can’t fully recuperate from separating from Mi Ka that catches the attention of his father.
Do Ha can’t stop thinking about Mi Ka. He visits her room and finds secret notes she has hidden in her doll. After reading the notes, Do Ha tries to piece together all of her thoughts and starts to figure out why she is avoiding him. Meanwhile, Su Bong meets with Do Ha’s father and tells him she is worried Do Ha will not come through with the wedding that drives him straight to Do Ha’s office.
Do Ha finds out that it’s him who loses time when he is with Mi Ka and waits for her at her door. Although painful, she still refuses to be with him and makes up her mind to leave everything behind. She meets with Director Cho and tries to tell him she is quitting the musical when suddenly, he calls for an urgent meeting with the cast that changes her mind. Meanwhile, Su Bong continues to try to convince Do Ha to marry her.
Su Bong’s last desperate appeal for Do Ha’s love fails. As Su Bong walks past Mi Ka, Mi Ka notices Su Bong’s time start to rapidly drop and quickly follows her to the rooftop. Knowing that the only possible thing Su Bong could be attempting is suicide, she calls Do Ha for help. Meanwhile, the musical starts to progress, and Wi Jin puts on a suit for an interview and turns up his charms for Seong Hee to notice.
With the musical finished, Mi Ka sticks to her promise with Do Ha and does whatever is asked of him. She forgets about the time that taunts her and makes the day as memorable as possible. However, her conscience can never fully let her forgot the outcome of being with Do Ha, and she makes a run for it. Soon, her mother finds out about her remaining time and does whatever it takes to save her—even begging Do Ha for help. Meanwhile, Mi Ka accepts her fate and lives her day to day when suddenly, her time starts to increase rapidly.
