Rikedan no Houteishiki ~Omae o "Ore" ni wa Watasanai~

Set in Japan, somewhat into the future.
Misaka Yue, who works at a major robotics company, has feelings for her eccentric and self-centered boss, Kakuregi Hajime.
One day, an identical Hajime appears! (He has none of Kakuregi's flaws, making him a perfectly lovable guy.)
He starts meddling in Yue's business and private life.
What will come of this odd office love triangle?
