When I opened my eyes again, I was back in the examination room during my senior year of high school.

The teacher frowned as he looked at the note in his hand, reading word by word, "‘Andreas, I don't know how to answer the last big question.’

——

“Who wrote this? Stand up!"

I woke up with a startle from a loud shout and found myself back in the examination room of my senior year of high school.

My childhood friend Andreas turned around and saw me with tears on my face. He sighed with pity, "Since you've already stood up, just... accept it."

Next to me, Avery, whom I had always regarded as my best friend, thanked me in a low voice with tears in her eyes, "Kristi, I will repay you."

I finally pulled myself out of the pain of my family being torn apart in my previous life and stood up before Andreas could speak.

“Sir, I didn’t throw this note. The ink on it is blue-black, but my pen only writes in black, so it couldn’t have been mine.

“Besides, the handwriting is shaky and messy and I always write neatly with little emoticons too. Also, I’ve already solved the last big question. Look, it really can’t be me!”
