One wrong number can change everything.Yoo I Seop is a quiet, reserved young man whose world shifts when he receives a call from an unknown number—one that wasn't meant for him. On the other end is Han U Tae, a bold and mysterious stranger whose voice becomes the beginning of something neither of them expected.What starts as an accidental connection grows into something deeper as they continue to talk, night after night. But both carry emotional scars, and neither of them has been entirely honest about who they are—or what they're hiding. When past traumas resurface and feelings grow complicated, they must confront their own fears before the line between comfort and pain disappears.Can a mistake lead to something real? Or are they destined to be two strangers, forever just a voice on the other end?Sometimes, the wrong number is the right person.(Source: MDL)
