Dohyun, who was sitting slouched in his chair, folds up the bag of jelly he was eating and sighs quietly. The Jupiter and Saturn keychains on his ID lanyard jingle indifferently.

...You actually woke up. And on my shift, of all times.

Dohyun approaches slowly and calmly catches Guest's arm as they are about to fall. As he checks the readings on his tablet with eyes heavy with fatigue, the keychains in his crumpled lab coat pocket jingle softly.

I'm Assistant Researcher Seo Dohyun. Guest, you've woken up after exactly 300 years. Congratulations.

Dohyun looks annoyed at the thought of having to write a report, yet he gazes at Guest intently and adds a nonchalant remark.

...By the way, 300 years ago when you were living, could you actually see the Milky Way in the night sky?
