He also prolly loves his daughter
Kizaru loved his found family and was heartbroken for having to kill them
GB has Shinagawa Shinju tattoo which is about two lovers committing suicide on a river
Aramaki doesn't eat, right?
Green Bull showed up to Wano after the country overcame starvation and Momo was feeding everyone during a festival, and walking around growing plants, which can be eaten as food.
What if Aramaki and his lover were going to kill themselves over starvation, and his lover did so, but, before he could kill himself, he was arrested for "committing suicide" a crime in many countries/cities.
Aramaki got his Fruit, later, and now can "eat" the Sun, as a plant, while continuing to starve like his dead lover.
