Since you like Death Note, I assume you will be interested in or have read Hikaru no Go? There are two male leads - one has dark hair and is serious and smart.

Angel Densetsu fits that description too...

Matsuri Special, but it's more about a girl(she kicks ass) than a guy
Ousama Game it's an oneshot, it's really fun and the guy(though it's blond, I guess) it's really cool
Immortal Regis might be worth giving it a shot
Vampire Knight has lots of cool bishies, but I guess it's impossible not knowing about it
