More Mystery For a Bunch of Existing Mysteries

So that was the tea. 

Now, I'm sitting here in the pavilion, healthy and happy, drinking milk tea courtesy of Sera, and enjoying the afternoon breeze. 

Everything is so calm, just the way I like. 

Well, if I ignore the fact that Sera was staring at me weirdly.

I squinted at her.

"What?" 

Sera also narrowed her eyes at me, looking at me with obvious suspicion. She didn't respond right away and just drank from her cup which almost irked me to death.

"Why do you keep staring at me like that? You've been at it since earlier. What's your problem now?"

She's so weird.

"How did you do it?" she asked.

"Do what?"

"How did you kill all those fish?"

Ah…

So that was what she was curious about.

I shrugged at her.

"I don't know."

"Bullshit!"

"I really don't know!" I retorted. "I can't remember all of it clearly."
