💚 SenGen Included 💜
A few fics that I love that include SenGen, but they are not quite the main focus of the story.

the bleeding's incidental by breathepurple (bleedpurple) The Kingdom of Science assumed that Xeno and Stanley were in a relationship, seeing how determined the soldier is to retrieve the scientist.

They discover that Gen's parents are terrible people that abuse him and decide they will do what they must to take the boy back with them in America. ⚠️: Mentions of abuse, mentions of neglect, eating disorder.
