We Are Not Lovers

At 21, Hyunjae has a secret partner. It’s a relationship that’s hard to explain to others—because their meetings revolve solely around s*x.
The partner who indulges Hyunjae’s every desire in bed is Nanyeong. Though honest only between the sheets, this man hides much about himself. Yet, as their relationship continues, it feels like Nanyeong is starting to develop feelings for Hyunjae.
Still, he never proposes a real relationship.
Why is that? Why won’t he say he wants to be my lover…?
“Hyunjae, we agreed not to get emotionally involved.”
When Hyunjae tentatively reveals his feelings, Nanyeong draws a line, treating their connection as nothing more than a s*xual arrangement. He even offers Hyunjae a large sum of money, as if to soothe the pain of rejection with cash—almost like buying off his heartbreak.
In the end, driven by his longing to be with Nanyeong, Hyunjae accepts the money.
What exactly are we to each other? Is my body really all you want?
