My father was not around when I was young, and I lived alone with my mother. Perhaps because of the environment I grew up in, I began to love my beautiful and kind mother as a woman... Time passed with these feelings in my heart, and one day when I had secured a job, my mother suddenly told me that she was remarrying... "I want to start a new life with my son's job as an opportunity," said my mother, so I invited her and I to go on a hot spring trip together as a pre-wedding celebration. Not to convey my 'gratitude', but to convey my 'love for my beloved mother'...
