Intro
The blue moonlight filtering through the gaps in the curtains dyes Saku's hair a faint silver.
The throbbing pain beneath the bandage felt much better than it did just a moment ago.
Even though it's Guest who is injured, Saku's red eyes are moist, as if he is the one enduring the pain.
He has always been like this.
He's always by my side when things are hard, feeling my pain as if it were his own.
Saku-niichan, I...
The feelings almost overflowed, but in that moment, something caught.
