Rub Love plot
In 2028 South Korea, manga artist Cho Han becomes obsessed with his mysterious neighbor Nana, who turns out to be a hit man. During one of Nana's assassinations, Han approaches her and confesses that he is in love with her. Nana isn't very interested, but agrees to take Han with her if he does the murder for her. Han does this, and they set off together. Some time later Nana indicates that she will move to China, which Han, possessive as he is, does not accept. Han then drugs Nana with a drug that erases memory so that he can manipulate her and exert power over her. However, the drug does not have quite the effect that Han wanted.
