After his family’s downfall, Damon wandered from place to place. Then, he hears that the position of private tutor for the innocent young master Eden is vacant.

From their very first meeting, Eden—lonely and unable to hide his emotions—blushes in Damon's presence. Convinced that if he gains Eden’s favor, he can live a comfortable life in the mansion, Damon confidently takes the job.

"From now on, I will stay here and serve you, young master."

But life in the mansion doesn’t go as Damon expected. The more time he spends there, the more he starts to feel that taking this job was a trap from the very beginning...

"I only asked if you truly see me as nothing more than your student and your employee."

Eden longs to find something beautiful. Damon seeks something that never changes.

What secrets lie within this mansion...?
