Wooohhh!! I found some kind of translation while surfing the net. I disclaim anything on this.
It takes place in the earlier arc when Tsuna and co. were training in the death mountain and Tsuna got sent into the hospital and all and Gokudera too because he was hit by cars while trying to visit Tsuna(i think its the ep when hibari caught a cold and tsuna got transferred into a scary wardXDD). Gokudera tried his best to pretend to be energetic in front of Tsuna even though he's hurt becausec he doesn't want Tsuna to worry about him. But somehow that caused Tsuna to be transferred to another ward instead cos he's too noisy. Haru told Gokudera that he's under a curse, and he would eventually harm Tsuna if the curse continues. The only way to stop the curse is to obtain a straw doll from Lambo, who refused to give it to him and even caused a big hoohah. Gokudera had to disguise himself as a doctor in the hospital, wearing a surgical mask and cloak(thingy, idk whats it called).
He then encounters Dino who couldn't recognize him and attacked him because of his disguise. Eventually Gokudera ran away using his dynamites, but he stumbled into Hibari's ward and interrupted his sleep; and Gokudera, already weak from he's previous injuries even before Dino attacked him, was attacked by Hibari. The dynamites from before caused a fire which triggered the hosing system in the hospital, the water then caused Enzo to grow bigger and collapse through the ceiling when Hibari and Gokudera are fighting. Both of them were buried under the rubble, Haru was kneeling (I think) at the ward door, and crying. Hibari managed to come out of the rubble, seemingly unscathed and left. Haru started to find Gokudera amidst the remains of the ceiling and found him severely hurt but still alive.
It was then that Haru confessed that she had lied to Gokudera about the curse, that she only wanted Gokudera and Lambo to get along, since they were always fighting. Gokudera, too tired to be angry, asked her why did she decide to tell her about the curse being fake. (and I'll try to translate this part in dialogue form, cos it doesn't seem right to write this in a third person view bleahs, sorry for weird translationXDD;; the 1st person's gokudera, yea
"Why did you tell me this was a lie, didn't I tell you this is none of your bu--"
"What are you talking about!?" and she looked seriously into his shocked eyes.
"If Gokudera-san's hurt, Tsuna-san would be sad! That's why Haru will stop that from happening!"
"...che, so this is all for the tenth huh..."
"and Haru will be sad too."
"even though you always say mean things to haru... always bullies haru... even though you are such a person gokudera-san... but you are still haru's friend, so..."
"now go back to your ward-- as much as haru would want to say that; But It's gokudera-san's fault that the hospital ended up like this..."
"Not hahi-- it's annoying! don't tell me weird stuff like this, stupid woman!"
"hahi! what did you say! Haru was being nice--"
"You're so annoying! Stupid woman, YOU STUPID WOMAN!!"
"HAHI!! Why did you say it twice?!"
"I can say it as many times as I like, stupidwomanstupidwomanstupidwoman..."
"Gokudera-san you-- you--"
"YOU ARE THE MOST ANNOYING ONE!!"
I think this is a sequel to KHR episode 17: Nyūin Saki de wa Oto o Kese (Don't Make a Noise When You're Hospitalized)
That was really funny.
Oh my gosh!! They are REAL. Amano-san, they are real. Gokudera x Haru is really possible. It's canon
I can see Gokudera being jealous when Haru said that it's for Tsuna's sake and he's hiding his feelings from Haru at the end (flustered). Haha...I'm so motivated by this. YOSH! Back to work
