The father bubble with him being supposedly dead is probably a translation error and it was probably grand father instead?
It was translated from chinese if someone can read the original here : https://i.imgur.com/S9tKUt8.jpg
Google TL for grandfather seems to match with the original page : https://i.imgur.com/4MJF0Z7.png
Did a quick edit just in case if the uploader can change the page : https://i.imgur.com/SlLcEPw.jpg
Edit : Someone on reddit confirmed that it is grandfather indeed : https://www.reddit.com/r/manga/comments/cf0lua/disc_5toubun_no_hanayome_itsuki_doujins_ch13_by/eu7kirp?utm_source=share&utm_medium=web2x
