Idk maybe im wrong but what i can say is candy's mission about the target have the blueprint, then candy lure hajun, fall in love, candy got new mission to kill hajun, candy couldn't, uno knew the truth about how dangerous the blueprint is and how their boss is actually up to no good, candy save the target (hajun's dad), few years later, target finally spill the beans about the blueprint is dangerous.
Idk if this makes sense but yes. I think.....

im kinda confused about the plot rn lmao can someone explain what's going on (╥﹏╥) maybe im just dumb but i feel like im missing something idk
