ADN-648 My wife and my father are taking a bath together. Tsubaki Sannomiya

A year has passed since I started living with my single father. My father has been suffering from severe back pain lately, and has started to hesitate to take a bath. He asked my wife to wash him, but I refused, saying that it was impossible. However, I feel like my wife and my father have become much closer recently. I don't think that's the case, but... my wife and my father don't take baths together, do they? No way... that can't be true...
