Symbiosis of Luna and Sol

Han Boreum just wanted answers about his mysterious illness—not a death sentence. But the shaman he visits drops a bombshell: "You're overflowing with dark yin energy. If you don't sleep with a man full of yang energy, you won't live long."

Desperate to survive, Boreum sets out to find his "yang-guy," and right on cue appears Joo Taeyang—campus heartthrob, top business student, and nicknamed "Apollo" by his admirers.

Perfect, right? Except... he's a two-faced jerk only when it comes to Boreum.

Still, with his life on the line, Boreum launches a clumsy, tear-filled operation to seduce his moody match.

Between awkward attempts at flirtation and unexpected sparks, Boreum starts to wonder—Could survival turn into something a little sweeter?
