Synopsis

Office worker Nakado Sumire, who grew up surrounded only by women, struggles with matchmaking events, failing each time because nerves keep her from holding a proper conversation. Desperate to experience intimacy at least once, she turns to her respected colleague Tachibana Kotaro – the only man she feels comfortable talking to at work.
 
Tachibana, who had secretly been in love with Sumire, agrees on the condition she’ll become his girlfriend. However, Sumire misunderstands, believing he just wants her to pretend to be his girlfriend in order to ward off advances from other women. The drama depicts how their relationship, born from this misunderstanding, gradually transforms into a true romance.
