You guys are getting all off topic !

Hmm so Manga about boys who chase after girls. Now for some reason it's really hard to find these among Japanese Manga. Looks like in most novels they have weaker male and strong girl character usually bully the poor boy like hell. But there are exceptions.
- Suzuka
A Manga I hard read long long time ago. A guy trying to win girls heart.
- School Rumble
I think you can take this one under that category too. It's a long manga, has about 250 chapters or more. But already completed back in 2008 or 2009.
