The uke is a contract killer (hitman) that uses a special pill, that gives him cryo (ice) abilities, to kill his targets.
The uke's ex was a good-for-nothing gold-digger and swindler who stole all of the uke's money and valuable and ditched. The uke moves into a penthouse where he lives with the owner. He ends up having drunk sex (dear lord help this person when he's drunk) and ends up becoming lovers with the owner (seme). The seme and the uke both find out the truth about each other at the same time.
