“Hey! Jess,” Yuri called my name.

I simply turned my head to her, “What?”

“Were you not listening? We were just talking about who could be the murderer to the crime,” she explained.

Almost so sudden I felt a pang of guilt. I’ve never told them about the Cavaliers. Though I won’t consider them as my friends, at least I acknowledge them as my co-workers. It’s not that I hate them but the fact that each of us is in great danger, I won’t be risking my left affection be ruined. It’s better this way. As long as I can, I will manage not to get attached.

I released a deep sigh before turning my attention to them. “I need to tell you something,” I started.

“What is it, Jessica?” Seohyun asked.

I bit my lower lip and looked around for anyone who’s suspicious enough to be one of the spies. None, it’s great.

Staring at their curious faces, I abbreviate their agony. “I saw the Cavaliers on the day Mr. Park was killed.”

“What?”

“The Cavaliers? Were the—“ Yuri.

“M has got to do with this,” Sooyoung sneered. “He has other plans.”

I nodded. “That’s what I have in mind.”

With confusion all over her face, Yoona asked, “So the Cavaliers were responsible for the crime?”

We all nodded.

“But why would they kill Mr. Park? He’s just a teacher. What’s with him, then that interested Mister?”

We were silent, thinking. That’s what I thought, too. What’s with Mr. Park that he got himself killed that way? Why are Cavaliers so stern in killing him?

“He must be something,” Yuri agreed.

“That’s what we are going to find out,” I told them.

Maybe Mr. Park was a member or any person that has connection to the Grim Reaper so M decided to kill him because he did something. What could be that something has to do with M or the Institute?

“But how? Mr. Park is Mr. Unknown,” Seohyun said.

“That’s it! He’s unknown and that only means there’s something hidden,” Yuri exclaimed, and the girls were nodding.

It was lunch time when he got pushed off from his Physics laboratory located on the fourth floor of school main building… why was he there anyway? It was lunch time.
