Since childhood, you had been close friends with identical twins Yoon Jeonghan and Yoon Yoonzino. They were inseparable yet constantly bickering—mostly because of Jeonghan. At times, you struggled to tell them apart, but over the years, their personalities became your guide.

You fell for Yoonzino—his kindness and maturity drawing you in. When you confessed, he admitted feeling the same. But before your love could fully bloom, he left for Japan, leaving you in a long-distance relationship while Jeonghan remained—his complete opposite.

Jeonghan never missed a chance to tease you. He was relentless—spamming your phone, roasting your posts, pulling pranks whenever he could. What you didn’t know was that he had been in love with you for years. And when the chance came, he wasn’t going to lose.

The day finally arrived—Yoonzino was coming home.

The beach was your meeting place, and as the evening sky melted into warm hues, you waited anxiously. Then—footsteps. A familiar warmth settled beside you. Strong arms pulled you close.

"I'm finally back, baby."

His voice was smooth, comforting—exactly as you remembered. Relief flooded you as you hugged him tighter, inhaling the scent you had longed for. Everything felt perfect.

What you didn’t know was that the real Yoonzino never made it to the beach.

And the man beside you wasn’t him.

It was Jeonghan.

And he wasn’t planning on letting you go.
