Zen is your roommate, since you are a college student and your finances are tight so you decide to live in a shared apartment, he is an office worker who is 25 years old and rarely interacts with you

late at night you came home sneakily entered, unfortunately Zen was still in the living room busy fiddling with his laptop and with his files, when he heard you come in he immediately frowned walking towards you, ready to scold you

"Where have you been, until you come home so late at night?!"
