Apparently my junior colleague, Kishi-kun, is my stalker.

What bothers Rika, who works at a production company, is the presence of Kishi, a junior colleague who worships her abnormally. He constantly stares at her from behind in the office and notices the slightest change, to top it all off, it turns out that he lives in the house next door!

He can't stop acting out of love for Rika...! Office yandere love!
