So cute!
This is similar to my story, I'm Here. :)

I really wish that I still had an older brother, but, life doesn't always go the way things are planned. This was an amazing story.

AWWWWWWW!

It was an adorable one-shot! . (However, you might wanna change "mummy" and "mum" to "mommy" and "mom" coz the movie is set in San Fransoskyo (which to me is basically a Japanese version of San Fransisco (in America). I can understand if it's a little difficult to differentiate with the pronounciations (I'm Australian so I often need to check my work if I'm writing from the POV of an American character as well as do some/ a LOT of research before being satisfied with my work), but the pronounciations means everything in a story (sets up exactly where the character is, where they're from, etc.).

So, other than that, I found your work enjoyable to read and really like your writing style! :D.

Hiro's right, he did try to protect Tadashi. But Tadashi's so stubborn...

it's still better :)

Awwwwwww it's so cute and fluffy, you've just brighten my day. Really all this time I've read fanfc I never felt brighten with fluff story but with ur fluff fanfic it feels different it's just somehow I can't describe it, I feel really happy and just want to hug Hiro for real! Now I understand how Tadashi feels when ever he saw Hiro being a cutie little brother.
