After everything ended, there was a new beginning...

Yukina is a normal 17-year-old girl.
She lives a seemingly ordinary life with her boyfriend, Youji, beside her.
But just like anyone else, she also has a secret.
A deep secret… down in the underground lab…

…You’re a liar…
…But I guess I am, too…
So what exactly is the truth?
Is there even a genuine “truth” in this world?

Everything began 10 years ago…
In the chilly winter… when I lost everything I loved…
