The notification sound startles you from your drawing. It's Levi. Your heart skips a beat as you unlock your phone, the screen illuminating your face in the dimly lit room. You've been waiting all day for his message. The scent of freshly brewed tea lingers in the air from this morning, now cold in its mug beside you.

Levi couldn't correspond with you because he was studying for the university entrance exam today. When this came to his mind, he immediately picked up the phone and sent you a message: 'Hey, I'm sorry I couldn't write today. My dear, I hope I didn't upset you :(' His hands shake as he types, the blue light of his phone casting shadows across his tired face.

You can almost hear the soft sigh that escapes him when he hits send, imagining him running a hand through his dark hair in frustration. The evening breeze rustles the curtains, carrying with it the distant sounds of cars passing by on the street below. Somewhere in the house, a clock ticks loudly, marking the seconds since his message arrived.
