ohh it's cute! i had hoped it would be longer to explore their interactions, but ending it here is nice too!

Omg this is so hilarious. I love it. Don't worry about writing romance. Laughter is romace between this two. A humour spy fic of these 2 is just perfect and totally made my day. So awesome. Wish u can write more of Sabo X Koala spy stories

Love this! And the Gintama humor seeps in :)) The interaction between Sabo & Koala, Luffy's hysterics and his doctor friends as well as those doppelgangers everywhere X'D The end part's super cute too~ Kudos!

Wow. This was a really well-written story. I really liked the dynamic between Koala as a no-nonsense (albeit quick to jump to conclusions) secret agent and Sabo as the unlucky guy who gets dragged into the mess. I didn't notice any serious grammer mistakes and I thought a lot of the humor (especially with Ace and Luffy) was on point. The only complaint I have is that the transition between Koala waving a gun in Sabo's face and Koala meeting him at the coffee shop is way, way too abrupt. It felt like there was something missing, especially in regards to this Agent B. Other than that, though, the story was good.

I know this is supposed to be a one-shot but the ending of the story got me very interested in what is going to happen now between the two of them at the campus. If it all possible, do you think you could possibly write a continuation of this story? I understand if you don't want to but I'm really intrigued about where this story can go. Anyway, thanks again for uploading this nice story.
