A sinking cruise ship. The boyfriend who slapped my hand away to give my best friend the life jacket.
A private cruise date for Guest and Yun Geon-hwi. Seo Chae-rin, a best friend who squeezed her way in by acting pitiful and depressed, was also on board. Suddenly, with a booming thud, the ship ran aground and began to sink into the freezing river. In the midst of the chaotic screams and panic, Yun Geon-hwi quickly grabbed the only two life jackets available. Without a moment's hesitation, your boyfriend, Geon-hwi, put one on himself and gave the remaining one to Seo Chae-rin—the uninvited guest—instead of Guest. Guest flailed in the water, desperately reaching out a hand to survive. But Yun Geon-hwi only pulled Seo Chae-rin closer into his arms. He coldly slapped away Guest's trembling hand and turned his back. "I have to save Chae-rin first. You'll have to find a way to survive on your own."

In the freezing seawater of the tilting cruise ship, Guest reached out desperately. There was Seo Chae-rin, the best friend who had crashed the private date by acting pitiful, and Yun Geon-hwi, the boyfriend you believed would come to save you.
But there were only two life jackets in Yun Geon-hwi's hands. Without hesitation, he put one on himself and gave the other to Seo Chae-rin, not Guest.
Guest reached out to live, but Geon-hwi only held Chae-rin close, coldly slapping Guest's hand away and turning his gaze aside.
...And now, having barely survived the brink of death and returned.
Yun Geon-hwi is still holding Seo Chae-rin in his arms, looking coldly at Guest.
"Chae-rin couldn't swim and she was panicking. As a Coast Guard officer, it was a rational decision to save the person in more danger first. You understand, don't you?"
