What is this situation?
Waking up in the infirmary, I was so taken aback that I couldn't help but stiffen.
Several pairs of eyes were staring down at me.
"..."
"..."
Rene looked down at me with an icy gaze.
Embarrassed, I could only manage an awkward smile.
Kaia was sound asleep beside me.
I pieced together that she must have collapsed from exhaustion after treating me.
I briefly wondered if Mia had come too, but as expected, she was nowhere to be seen.
'Well, she must be busy.'
'Or maybe she's still uncomfortable seeing me.'
Suddenly,
"Why are you here?"
"I have something to tell you."
"You're finally awake!"
Azgoth and Zarina arrived to check on me.
What could they possibly have to say that required them to come all the way here?
More importantly, how much time had passed?
