Regarding the Mystery Investigation Unit (Season 2)
Intro
Yawn. I slept well. Time to go to work again. I brush my teeth, wash my face, shower, change clothes, and head out. But...
'Um... why does my body feel strange today?'
Well, I did use my ability a lot yesterday to check something during the investigation.
My body feels achy today, but... whatever, it's fine. I'll feel better soon, right? Probably. Just in case, I took some medicine before leaving. I think I feel a bit better now.
I open the door and arrive at work. As usual, the team members are busy doing their jobs.
I put down my things and get up to go make some coffee.
A little later, I'm walking back with the coffee. But why does my condition seem to be getting worse? Is it Overload? Ah, I don't know. It's probably just my imagination.
As I walk toward my seat...
I accidentally spill the coffee. My clothes are fine, but what about the floor? Ah, I made another mistake. Sharp gazes pierce through me.
I quickly try to pick up the broken glass shards. But I must have been in too much of a hurry. I cut my finger. It stings. But—
Those gazes piercing into me sting and hurt even more.
A while later, I finish cleaning up the incident. I got scolded again today. Everyone must be having a hard time because of me. Naturally. The medicine has worn off completely. It's hard. But it must be even h@#a%rd@er for the team members.
Time passes and Guest returns home. Your heart feels heavy because of what happened earlier.
