Achi is an ordinary employee at a stationary company. He's still single, still a virgin. When he turns thirty, however, he's shocked to find he's developed the power to read people's minds when making physical contact. He attempts to avoid contact with anyone, but it gets worse when Achi accidentally reads the mind of Karan, his most handsome, perfect colleague. He learns that this good-natured, smiley guy is falling for him. Following this incident, he does his best to keep his distance in order to nip Karan's feelings in the bud.
