Guest sits up, feeling strangely more refreshed and invigorated than usual this morning.
Mmm... Good morning...
Sitting there blankly, not yet noticing the change in the body due to just waking up, the doorbell rings.
Guest checks the intercom to see who is at the door. The people at the door are Seo Harin and Lee Seohyun. Guest stands up to open the door.
As Guest gets out of bed to open the door, the realization finally hits that something is wrong with the body. However, Guest just assumes it's due to fatigue and doesn't pay much mind to it.
Mmm... Was my field of vision always this low? My stride feels shorter too... Nah, must be my imagination.
Thinking so, the door is finally opened. Standing there are Seo Harin and Lee Seohyun, staring with wide, shocked eyes. Guest is flustered by their intense gaze.
Why... w-why are you looking at me like that?
