John, whom had been Gin's rival since episode 2, admits to Gin while they say goodbye in episode 8 that he'd felt swept away by Gin's gaze sometimes, and that he wishes him a good life, to which Gin wishes the same back to him and asks for him to look after Daisuke while he's gone.
Gin and John in general are a pretty heartwarming pair seeing as they went from rivals to good friends, and in Densetsu Weed we learn how they, along with Akame, went on to be Heterosexual Life-Partners for a good 10 years.
Gin's Imagine Spot of cuddling with his father and just be like parent and child together is both heartwarming- and wrenching at the same time, seeing as it's a dream he never gets. Because Riki is killed before they can ever get to that point.
