I understand how they could look similar... But not so much that they would be brothers. More cousins than anything else, first or second.

Interesting! The concept definitely gives the imagination a lot of stuff to work with! The subtle way you brought out the relationship between the brothers was great too!

I like this chapter I hope u write another fic story about in with more than one chapter

I love the thought of the two being related Cx
I also wanted to tell you that Aneue is a way to address an older sister and Aniki is for men lol

please make more of this characters (hibari & haruka)

This One-shot deserves a Cookie. *hands the author one*

I really liked this. It was fun. As for continuing this, maybe you could have the KHR gang come to cheer on the Iwatobi team at their swim meets, maybe that really important one that I forgot its name. The nationals, maybe? Haruka could try to convince Hibari to come and cheer him on and the KHR gang walk in on them and then they all end up coming to the meet. Hibari can be really bitter as he watches his brother and Tsuna manages to make him tell him what's bothering him. Then Tsuna can cheer him up by saying that Hibari is good at fighting and his brother isn't. Then mafia gets involved and Haruka sees what Hibari sees in Tsuna. When it's all over Haruka can say something like, "I'll leave my brother in your hands," or something like that. Maybe some Free! and KHR character interaction in between, I guess. It's just an idea, you don't have to write it. Anyway, this one-shot was great. Thanks for writing it.

Very interesting story! :D

are you going to continue? Please do because this could make a really good story!

This could maybe be a drabbles thing :3 me liiiike -w-

That was EPIC! Can you possibly make a sequel?

im laughin so hard omfg
swimming prodigies like u
im choking omg

Definitely continue. This stuff is gold

Hahaha, amazing :D Honestly I started watching Free! just because Haru-chan looks like Hibari, and lo and behold, they even have similar personalities, so I immediately located this fic. Thank you for writing this! Apparently Hibari has always won lots of reader polls for favorite and strongest, and he's even topping the character-I-would-marry list... So I wondered if maybe they had based Haru's appearance on him a little, on that basis.

Hahahaha, this was kind of weird, but still i like it... And util now i have not thought about how similar they are... Hope you continue it...
Sorry for any mistakes English is not my first language,
and is this history maybe... become yaoi? or have pairings?
