The Cleaner Who Was a Janitor

Zane Sterling sneaks into Emperor Group, intending to apply for a janitor position, but accidentally stumbles into a business department interview. He improvises a bold performance, and is mistakenly identified as "The Cleaner." His act of turning off lights is interpreted as enforcing discipline, and watching anime as decoding hidden business opportunities. The company worships him as a legendary figure, and a domineering female CEO and wealthy heiress fight for his affection.
