I feel like something is missing or like it's missing a couple of pages from the climax(or when there was a problem). I know that when they flashed back he kissed him when he was drunk but they NEVER showed that after he actually got drunk in the chapter and it just stopped. They never discussed there is an issue in their relationship besides the childhood thing. AND THEY DIDN"T EVEN TALK ABOUT THAT. Idk the story just feels incomplete.
