The second installment of the drama series about a mother and son in the steam, shot and drawn by Koichi Takahashi, the most important figure in travel pornography. Originally, she was a very beautiful woman who worked as a secretary at my father's company. That's my mother now. I have never called this person 'mom' until now. It's been 10 years since then...with a sudden chance, I set off on a hot spring trip without bathing.
