It's not the first pairing that comes to most people's minds - but I'm very glad you gave it a chance even so! And that you enjoyed the story. :-)

i was imagining Ryo and Taguchi from Ganbatte ikimashoi >< the character they have in this story matches those 2's personalities well

They definitely did have an interesting dynamic going! I would love to have slash fanfic for Ganbatte.
