I'm looking for ...

BRIEF
a) Important male character that has a one-sided crush on a male main character
b) Mangas aren't shounen-ai or yaoi

DETAILS
I'm looking for a gay one-sided crash on a main character in any manga that is not shounen-ai/yaoi. I don't want the random guys that just randomly confesses their love to main character (then never seen again). It has to be somebody that main character is often around with, such as the supporting characters, villains, etc.

His attraction won't develop a romance with main character. It's one-sided. And it's not main feature in the manga. I prefer main character to know this but I don't mind if he's being oblivious.

For an example: Akito in Air Gear. He has a crush on a main character (and main character knows this.) But nothing'll happen out of it as the manga's not about shounen-ai/yaoi.

Mirai Nikki

just by reading the title i immediately think of DNAngel

maybe Shinshi Doumei Cross the vice president like the president (actually an impersonator) but the president like the heroine...

The manga: Obaka-chan, Koigatariki (shoujo)

The guy is his classmate, you'll definitely see him along the way 😀 fufu

I second Shinshi Doumei †.

There's some of it going on in Shitsurakuen, though it's directed towards main antagonists.

Kyou Kara Maou! / Kyou Kara Maou! (Novel), though it's more for comedy than drama.

blaue rosen the two most often shown male side characters
kuroshitsuji only in the anime since grell only appeared once in the manga.
mirai nikki and shinshi doumei cross were already mentioned

Okama Report

Something like that develops in Midori no Hibi

"It is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science."

...hmm Atashi wa Bambi perhaps?The main character(girl) falls in love with a guy whose best friend is also in love with him.

For a moment there I thought I lost all faith in humanity.
Thankfully someone already said Mirai Nikki at the top. xD

haha this i suppose?
Kunisaki Izumo no Jijou

KanataxYuki will always remain in my heart...
Their love is so profound~!
