Memory?

After the short war occured, Krova lost his half of his memory and even the memory of what happen before war is also vanished from his mind.

"What happened? Why I did not remember anything?"

Even the memory with his family and friends, he can't recall even a second of moment. He regain it back after looking at a few picture of his family photo.

After what happened, he dropped out of college and continue living at the Moscow alone and rotting in his apartment trying to remember who he is.
