The daughter-in-law fell in love with her father-in-law

My father passed away early when I was a student and my mother got married to a new man this year. He is over 50. At first, I didn't think it would be my father because in my heart I couldn't forget my biological father, but then Seeing the suffering and sacrifice to take care of my mother and child, I fell in love with him and my feelings grew until one day.
