it says "after that day 6 yrs ago, dad always went to Mom's hopsital late". He is seen with that box of flowers which indicates that that day, he saved blonde. So basically he wasnt going with other women those days. But it said "always" so im supposing he went to check up on how blonde was doing everyday???? Even though that was never mentioned bc blonde even said he cldnt remmeber the face of the man who saved him??? Hence, I think the dad shldve only been late to the hospital once. But what was he doing the other days? Going with what the mom said, of the women that the man fell in love with, seems like that is not fake anyways (?) Bc the man himself said he made mistakes.
Nice main couples story,
I wish there would be a spin off of the yakuza leader !
