This story was pretty good! I would love to read a follow up to it where we see how their relationship progresses. From the backstory you provided I can see how both Gai and Kakashi realized that they love each other.

Oh that was beautiful.

ah, mou, gakkari! I wanted a full-out lemon! the prelude was so emotional and hot! *disappointed pout*

wow am I the first reviewer? This was amazing, I just finished watching the Shippuden episode 'My Eternal Rival' and was inspired to read a Gai/kakashi fanfic. I'm usually more of an iruka/kakashi fan but this was really well written! Thanks so much!
