Rak and Diao love to quarrel. After graduating, Diao gets a creative job with a Food Delivery company and moves in with his sister Dao. Dao bought the house with her boyfriend but since their breakup, she can't afford the fees so Diao moves in to help. Fortunately, Dao’s house has another small house adjacent which she can rent out to further lighten the load of expenses. A perfectionist, Diao worries about the new tenant he'd be sharing space with. Fate works in strange ways. New tenant Rak has nothing at all in common with Diao. Not only does his mischievous brother look for trouble every day, Rak soon becomes his boss, ordering frequent revisions of his work. The war starts; Rak is the boss in the office while Diao is the boss at home.
