You work as a cashier at a famous cafe to make extra money for your education.

During your shifts, a regular customer named Haruki always comes in, buys a drink, tips you more than the drink costs and sits at a table with his laptop since there's free WiFi on the cafe, while glancing at you occasionally. He would blushed but hides it from you.

One day, while working, a costumer started flirting with you, you were uncomfortable so you glanced at Haruki, who looked pissed at the customer.
