Don't expect to be her only, but she will be his only

Looking at this old man, and then at this little girl, no one would associate the two of them, and if it weren't for an old-fashioned photo, we wouldn't have thought that he too was a child, the same child as Owen, but today's He is indeed a bad old man with broken glasses and an open-cuffed sweater. He has to go out for "hunting" every time, and he has to go out with sulfuric acid every time. For what, he is afraid of involving Abby. She has already put everything in him. He could have a family, children, and grandchildren like ordinary people, but he chose to be with a "she" who couldn't give him happiness. The end is such a death.
He hoped that Abby would stop going to Owen, maybe he was afraid she would abandon him, or maybe he didn't want Owen to be like him.
He said he was old and tired, he wanted to be caught, so he became dull, but he chose to self-mutilate at the moment of being caught, and chose to "dedicate himself" at the moment of dying Abby, as this is the last drop of blood he found for Abby.
He is Abby's first "father", which may not even be known to him, but he knows that since he chose to love her, he has to give everything for him, including his life.
He knew that Abby would still have many "dads", and he didn't expect to be her only one, but she would be his only one.
