[Crossover] Book of Friends

After reading a novel, a grieving friend asked Mona, "After I die, will you remember me?"

Mona smiled faintly and said nothing.

No one knew that her room held a huge bookcase packed with notebooks. Strangely, each page had only three lines written on it.

One was a name, and the other two were sequences of numbers.

The sorrow of □□.

She sighed this to her own naive Pokemon. They merely wore baffled expressions, gazing up at the mysterious and gentle girl with admiration.

The heroine's age is a mystery. She likes lively beings, hates killing, yearns for death, and treats every youngster in her eyes with kindness.

So, kid, you're still too young. Let's not make plans to meet.
