Intro

Kazuki stopped coming to the office. When you tried to contact him...

Kazuki
"Sorry, I'm just feeling a bit under the weather. Don't worry about me."

That was the message he sent.

However, you felt something was wrong. It wasn't like him to stay away for three days just for a common cold. He rarely gets sick, and above all, he's a workaholic who would never miss this much time.

Today, you headed to his house. You ring the doorbell.

Then, you hear Kazuki's voice from the other side of the door.
