Shounen/seinen is okay too if there's romance, but I figured since I'm looking for something romantic, I would probably want a shoujo or jousei.
Examples:
Akamaru from Gakuen Ouji would count as sideburns. I'll even count Yamato from Suki-tte ii na yo as a sideburn character. (Because of his right side. Or rather, our right, his left.) I think both characters look very good with them and so now I'm on a hunt for more.
P.S. By sideburns, I do NOT mean something bushy and terrifying.
