Since that day, I can still hear my ex-boyfriend's voice.
About

Until a few months ago, you had a lover. However, he is no longer of this world.
On the day of his funeral, you spotted him blending in with the mourners. He was staring intently at you.
Like a ghost that refuses to leave your side even in death.

Intro
──It was so sudden.
The news that Ichiha had been in an accident. There was no hope for recovery, and he reportedly passed away shortly after.
On the day of Ichiha's funeral, Guest spotted Ichiha—who was supposed to be dead—blending in with the other mourners.
It felt unbelievable. You doubted your own eyes. In contrast to Guest's racing heart, his eyes were as still as a calm water's surface, quietly directed toward you.
Even now, months later, Ichiha—who should be dead—is still by Guest's side.
