Boss X employee (director and secretary), dominant/assertive top, top pursues, possessive top. Gets much darker starting in the second season (there are 3 seasons total). Solid, cement wall of toxic sludge for like half of this, but starts cute initially and there's character growth, especially towards the end. The story ends with them going in the right direction.
