Well... It doesn't seem to me that Satomi swing that way.. though it's true, he's overprotective only when it comes to Shino..
It's like, in Satomi's eyes... Shino is still that little child who keeps calling him " Nii-Nii ". Remember how he said that time Shino revert back to his true form?
Satomi said, " That's right. I always forgotten, that you are actually an 18 years old. "
So for me, he was just quick to baby Shino because of how he adore him so much as an older brother for Shino. Satomi loves to spoil Shino eversince he was a kid, so it's just a natural act for him.
Satomi is just seeing him as a little brother. He was just like acting like a parent to him too.
Unlike with the shippings toward Ao, Sousuke and Genpachi.. You can really feel the BL atmosphere surrounding them.
I really love this shipping, hahaha. <3
Sousuke x Shino - What a brotherly love, a shounen ai type. (▰˘◡˘▰)
Ao x Shino - An incest brotherly love, though they really not blood related. (▰˘◡˘▰)
Genpachi x Shino - This pair is really my fave!! I have so many expectations. Damn.. I wanna see Genpachi's reaction when the time comes he finally see Shino's true form, Shino's 18 year old form!! Hahaha can't wait to see it. (▰˘◡˘▰)
