Rain and the Coder's Peace

Weighed down by his family's debt, reclusive programmer Hiki Kitoshi has engineered his life for total calm, though a grim glimpse of the future warns of heartbreak ahead.

Hiki soon understands she is his Zero-Day Exploit, the bug that will pull him straight into the emotional wreck he's been avoiding.
