Taking You in Hand (Yin Tu/Short)

I've been assigned to write about two yandere brothers~~~ Eek, I've never written yandere characters before. I looked it up, but I still feel like I can't quite get the hang of it. The characters may be OOC in some ways, but I'll do my best to make sure this is still a Gintoki/Hijikata story... It's told in the first person by the homeroom teacher, Sasaki~ Why Sasaki? Because I wanted to put him through some angst QVQ~ That's about it XD. My writing is poor, so please feel free to point out any problems XD~~ Theme:
