I don't think it's a dark story because in the end both of them got happy yeah the fact that the Seme had a hard time for the accident when he was still a kid was really sad. Honestly I think they could avoid to u up add the fact that the Uke used to be a maturation materia in high school but Uke is la real precious character, I could never imagine the Seme to be jealous wow he is the possessi type but that's kind of great. The romance in the beginning wasn't much but it ended with full of Shojo parts
Hard X Heat X Heart
