Out of My Depth

Synopsis

Jeong Haedeun, a former high school competitive swimmer, now lives a quiet life working at a local swim center. His world is upended when Han Sio appears, spinning a desperate web of lies about a career-ending leg injury that supposedly prevents him from ever swimming again. Moved by pity and a shared history, Haedeun falls for the deception and allows Sio to move into his home.

However, Sio’s motives are far from innocent. Having harbored a dark, obsessive crush on Haedeun for years, he views this cohabitation as the ultimate opportunity. Sio relentlessly pushes boundaries, his subtle manipulations eventually giving way to raw, unfiltered lust. He no longer hides his true nature, whispering feverish, provocative desires to his senior:

"I want to spend all day tangled with you, kissing you... I want to sink into you and fill your inside with nothing but me."
