At 30, his world is a gray-scale loop of overtime, convenience store meals, and a growing bank account.

One accidental moment-shatter Ken's assumptions. As Stell pulls away and a toxic shadow from his past reappears, Ken has to decide: Will he keep saving for a future that might never come, or will he finally spend everything he has on the one person he can't afford to lose?
