You were fairly close. It's still gibberish. It's poorly written, and it says heart one person fire fire or heart one person blaze (the last two kanji, which are repeated, are written like two kanji, but could be someone very awful at writing kanji's attempt to write one kanji that has "fire" in it twice: 火火 vs 炎). I bet he was trying to say something about how you're the one person for whom his heart blazes. Assuming that, what he wrote is read こころひとりほのお (kokoro hitori honoo). But it is gibberish.

It's just another example of a noob trying to be cool by writing Japanese. I did the same thing when I was 12 years old, lonely, and bullied.

Well, he tried then. I think that's kind of cute, even though he wrote gibberish. He tried writing something sweet in a language I could not understand in stead of having the guts to say it in my face. :D

But.. How would you write this correctly then? How would you have to say in Japanese that a certain person is the only one for whom your heart blazes?

You remembered the characters correctly, but it still is meaningless to anyone but him.

Heart/soul

single person/alone

flame

Well, I wonder what it was he really meant to say then. Maybe KyleGoetz was right about his idea of what it was supposed to mean.

Still, I wonder how you would say in Japanese that a certain person is the one person for whom your heart blazes.

Anyone?

心に火のように熱かせる1人
It's a bit dictionaryish, but ALC gives 心が火のように熱く as "the heart is a fire," so I just converted it to causative form and added "one person" to it. I sure as hell would never try to pass it off as good Japanese, though. It's quite difficult to translate phrases meant poetically from one language to another without it sounding weird in the language.

The phrase is "lost in translation."

Thank you very much! I don't know any Japanese yet (that's why I'm going to school to learn it this year), so having the "one person" part added to your translation, what does the meaning of it come down to?

I'm sorry. I'm still a total noob at this.

What?So what good are my suggestions doing?

If I already knew Japanese, I wouldn't have needed anyone to translate this for me in the first place would I?

Also, I thought it was pretty obvious that I don't know any Japanese yet as I already said I'm going to school to learn the language this year.

Anyway.. Could you please just tell me what i心に火のように熱かせる1人 means?
I'm trying to understand.

You've apparently never studied a foreign language before. There are degrees of knowledge of a language. For example, I definitely know and speak Japanese, but I sure as heck can't read the Bible in Japanese! I would need help understanding phrases, and that's an essential method of improving my knowledge.

Don't confuse the issue. My point was that you have never studied Japanese, so why should I help you? You misconstrued my point as something different: whether you speak Japanese. There is a huge difference.

It means what you asked for. You asked for a translation, I gave you one. Why would I give you something else in Japanese you didn't ask for?

Heck, I even referred you to a dictionary entry for about 90% of what I said.

Why not? I'm not welcome if I don't know any Japanese?

I meant could you please tell me the words as I don't know those characters, so I can't pronounce what it says.

I'm sorry I don't know any Japanese, but I really want to learn. :)
