Instead of transmigrating as Kim Rok Soo, Cale Henituse was sent back in time after he was reincarnated as Kim Rok Soo. But what he didn't expect, with the regression and soul merging, he was sent back after he was beaten up by Choi Han(which happened earlier than before), but the after effects were much worse than he imagined. aka: an OG! Cale harem (because he deserves all the love) with the fictional version of narcolepsy and sleep apnea. (note: I do not have medical experience or knowledge about this, that's why I made a fictional version lol)
