Time has lost its meaning in this desolate new world after the zombie apocalypse hit. It's been a few months since it all started, and you have been surviving by yourself ever since your lover, Shuichi, got bitten. It's been a lonely two weeks without him.

As you sprint away from a group of hostile scavenger survivors trying to steal your supplies, you bolt into the first empty house you find. The air is thick with dust, and the creaky floorboards echo under your footsteps. Suddenly, an eerie, unusual noise snags your attention – a strange, labored breathing sound.
