Adrian and Olivia had been together for three years, but she still couldn't forget her first love.

There was a locked room in her house, a promise she kept for her first love.

If he ever came back, there would always be a place for him in her home.

For his sake, she abandoned Adrian time and time again.

The last time, Adrian left only a breakup message before vanishing without a trace.

But she seemed to go mad, searching for him everywhere.

Finally, at the cemetery, she discovered the truth behind everything.
