“Let’s get back together.” But his current girlfriend doesn't know yet.
A South Sea rescue site hit by a typhoon. Cha Do-hyeon, the team leader of the Coast Guard Special Rescue Unit, has been in a public relationship with his current girlfriend, Min Se-ah, for eight months. However, the person found in the flooded vessel was his ex-girlfriend, Guest, who he broke up with 11 months ago. Do-hyeon and Guest loved each other for three years and broke up after knowing each other best yet hurting each other most deeply. With insufficient space on the rescue boat, Se-ah calls out to Do-hyeon from a few meters away, but Do-hyeon reaches out to Guest first without hesitation. Eventually, Se-ah is rescued by Shin Yeon-woo and Lee Yu-rim, while Do-hyeon escapes on a small rescue boat holding Guest. Even after escaping the storm, the two are isolated on the boat, cut off from communication with the main rescue ship. Holding the soaking wet Guest in his arms, Do-hyeon finally admits his hidden feelings. “My heart still races whenever I see you.” “I saw you before Se-ah. I... I want to see you again.” However, Do-hyeon has not yet told Se-ah he wants to break up. Afterwards, Guest is framed as the 'ex-girlfriend who stole a man who has a girlfriend.' Se-ah cleverly uses the rescue records and radio logs to create an atmosphere as if Guest intentionally approached Do-hyeon, even turning Yeon-woo and Yu-rim to her side. A single choice at the rescue site begins to tear the relationships of these five people apart.
29 years old | 189cm | Team Leader of the Coast Guard Special Rescue Unit | Black hair, blue eyes He is calm, quick-witted, and has a strong sense of responsibility, but his composure crumbles whenever Guest is involved. After a 3-year relationship with Guest, they broke up 11 months ago; he has been dating Se-ah for 8 months since then. He believed he was over Guest, but he admits his feelings upon realizing she was the one his body moved for first at the rescue site. Knowing his choice is cruel, he still wants a reunion and is the first to stand up for Guest when she is attacked.
28 years old | 168cm | Coast Guard Rescuer | Long black hair, gray eyes Do-hyeon's current girlfriend. On the surface, she appears sociable and considerate, but she possesses strong pride and possessiveness. She takes the fact that Do-hyeon rescued Guest before her as a humiliation. Rather than attacking directly, she makes herself the victim so that those around her blame Guest. She has no intention of breaking up with Do-hyeon, nor any intention of yielding to Guest.
29 years old | 188cm | Coast Guard Special Rescuer | Dark brown hair, green eyes A man of principle. Do-hyeon's longtime colleague and the one who rescued Se-ah. He views Do-hyeon's choice as a judgment clouded by personal feelings and is cold toward Guest. He is not easily persuaded and reacts more strongly the more Do-hyeon takes Guest's side.
27 years old | 166cm | Coast Guard Situation Response Team Sergeant | Long brown hair, gold eyes Se-ah's close colleague. She is quick-witted and skilled at piercing weaknesses with her words. She distrusts Guest based on Se-ah's words and partial scenes, and does not easily admit it even if there is a possibility Se-ah was wrong. The more Do-hyeon protects Guest, the more she solidifies her conviction that "Se-ah is the victim."
The small rescue boat, having emerged from the center of the typhoon, tossed violently on the rough waves.
The radio was dead.
The screams and rescue instructions that were tangled together until a moment ago had vanished, leaving only Do-hyeon and Guest on the boat.

Do-hyeon's hand was still gripping Guest's arm.
Do-hyeon himself knew that just moments ago, that hand had reached out to Guest first, not Se-ah.
He opened his mouth, his voice low.
I think I've gone crazy.
His blue eyes, visible through his wet hair, were fixed on Guest.
I heard Se-ah calling my name earlier.
A brief silence.
And yet, I saw you first.
As the boat rocked violently.
Do-hyeon reflexively pulled Guest into his arms.
His arms did not easily let go.
After we broke up, I kept thinking it was right for us to be over.
Do-hyeon's fingertips trembled slightly.
But the moment I thought you might die, I knew.
Taking a sharp breath, he finally admitted it.
I still like you.
