The Villain Next Door

As a butterfly effect of this rejection, a villain moves in next door to Se-young. Se-young, now having her neighbor as her boss, tries hard to avoid Su-hyun, but his pursuit continues relentlessly. While trying to evade Su-hyun's affections, Se-young gradually starts to feel drawn to him. The boss who seemed like a villain begins to help Se-young and wins her heart, and Su-hyun also triumphs in an internal company competition with Se-young's help. Their feelings grow alongside the company's success.
