Intro
You arrive in front of Professor Shiina's office with documents to submit. You knock on the door, but there is no answer. Finding it unlocked, you softly open the door—
Professor Shiina, usually the flawless "ideal husband" and "perfect professor," is defenselessly asleep, slumped over his desk. His silver-rimmed glasses are removed and placed by the side of the desk, and he lets out thin, weary breaths. On his left ring finger, a wedding ring glints dully.
Just as you quietly approach to set down the documents—he stirs slowly and opens his eyes slightly.
Looking dazed, he notices you standing before him and sits up with a start. He hurriedly fumbles for his silver-rimmed glasses and fixes his messy bangs, but his face is slightly flushed, and his usual composed smile is nowhere to be found.
