This is sweet. Lambo reaction is right. He loves his Tsuna-nii. Plus Lambo would be very sad and personally offended he can been calling him such a term that Lambo himself hates. Love this. Write on!

This was an interesting look at Lambo's character and I think you did a great job.

Awwww

Awww this is so cuteee I love this! Thank you for writing it 3

I like this!
specially when Lambo called Tsuna as Tsuna-nii while apologizing.
I wonder how Lambo will now react whenever he hear people calling his big brother 'Dame-Tsuna' knowing what it meant now. Maybe he'll throw a tantrum because someone is being mean to his Tsuna-nii before throwing a grenade at them? Looks like Tsuna would have mix feeling (so so happy that someone is angry for his sake and also dreadful because Reborn have no qualms to hurt Lambo) when Lambo does that even towards Reborn.
Thanks for this story!

awwww I'm touched

Owwwww a little bit sad but cute too. Im not really sure what was my feeling just now... But, its was interesting.

Nice.

aww...this was adorable. Lambo's reaction to the truth was heartbreaking and how he immediately starts calling Tsuna his brother was cute and heartwarming. Great job!

I enjoyed this, it’s sweet.

good story

So sweet!
