Zero-ka Hyaku-ka no Igarashi-kun

Overview

Hanamori, who works at a sports apparel manufacturer, is troubled by her own personality: overly sensitive, jack-of-all-trades, master of none, and a people-pleaser. Igarashi, a colleague who is cold and unkind to everyone, is the complete opposite of her... or so she thought, but then one day, he started to pursue her with full-blown doting affection!? It seems Igarashi's feelings for people are either "zero" or "100." In a conference room alone, in a cramped elevator, under the table at a drinking party... Igarashi's 100% love, unabashedly expressed without hesitation, has Hanamori at her mercy once again...! A polarizing colleague and a troubled people-pleaser - an office romance that erupts in an instant!! (Source: Kadokawa, translated)
