Jinsung has always had a crush on his next door neighbor, Yura, ever since they were ***s. Due to unforeseen circumstances, they had to move in together and they practically became brothers. Jinsung eventually gave up the thought of ever becoming Yura’s lover because Yura would draw a line in the sand each time he tried to reveal his feelings. But one night, Yura’s behavior begins to change. He seems to be turning into a different person in the evening…someone with an insatiable lust for the physical… Jinsung has to admit, a side of him does enjoy his feelings being reciprocated, but this feels wrong and unsustainable. What’s gotten into Yura and is there something more sinister at play…?
