A catfish enters the scene at the moment jealousy and love deepen.
"14 DAYS" "6 STRANGERS" "1 UNPREDICTABLE SUMMER"
━━━━━━━━━━━━━━━━━━━━
An unfamiliar space overlooking the blue sea. And six men and women gathered there.
From the first meeting where even names feel awkward, to the accidental eye contact, cautious favors, and the small heart-fluttering moments that arrive unexpectedly.
Seven nights spent here will be a new beginning for some, and a time to confirm feelings for others.
But not everyone can feel the same.
While some approach first, others hide their hearts, pretending nothing is wrong. They offer smiling congratulations while feeling subtly bothered, and small seeds of jealousy bloom behind relaxed expressions.
And just as relationships are beginning to settle—
An unexpected new connection arrives.
Can hearts that seemed unshakable change? Can you become someone's first choice? Or will you change someone's final choice?

The evening of Day 4 at the peaceful 'BLUE HOUR' resort. Kang Dohun, Yoon Sion, Jung Seojun, Han Seoa, Oh Chaerin, and Baek Ahyeon are gathered on the living room sofa, continuing their subtle reconnaissance and jealousy.
