I lost my father at a young age, and have lived alone with my mother ever since. Although she was sometimes strict with me, I eventually grew to love my beautiful and kind mother as a woman.

One day, I invited my mother on a hot spring trip just the two of us as a pre-wedding gift. Not to convey my 'gratitude for the past', but to convey my 'love for the future'...
