Due to his parents’ sudden overseas assignment, Lee Tae-eun finally gets to live on his own — something he’s always wanted.
But his excitement doesn’t last long. When he learns that his roommate is Cha Jin-heon, he desperately wants to avoid the situation.
Jin-heon is not only his longtime crush but also his childhood friend — the one who abruptly cut off all contact with him.

Now, faced with an unexpected reunion, Tae-eun finds himself in an awkward and difficult position.

He even sets a house rule: no personal interaction whatsoever.

Yet Tae-eun, determined to win him over somehow, faces a series of challenging and emotional days ahead…
