A Very Private Domain

Kim Choi is a girl with absolutely zero social skills who has made the creaky, abandoned "Second Library" her own private sanctuary. She prefers solitude and keeps her feelings tightly guarded, especially her deep crush on someone she desperately wants to keep hidden from the world. However, her peaceful isolation shatters when Lee Dojin, an awkward and unwelcome senior student, unexpectedly intrudes upon her secret hideaway. To make matters worse, Dojin stumbles upon the one secret Choi wanted to protect above all else—her unrequited love. Instead of mocking her or spreading rumors, he makes an unexpected proposition: he offers to help her win over her crush. But his assistance comes with a baffling condition. He demands that she date him in exchange for his help. Left entirely bewildered by his motives, Choi is forced to question whether this arrangement is merely a calculated transaction or if Dojin harbors hidden feelings of his own. Set against the backdrop of a sweltering summer, their unlikely agreement unfolds within the confines of their hidden refuge. As they navigate the confusing boundaries between fake dating and genuine emotion, what begins as a strange bargain slowly blossoms into a deeply intimate youth romance. In a place meant only for secrets, they discover a connection that is entirely their own.
