I am new so this is my first post well i am looking for:

>a manga where the girl has a chance to become famous but has to dump her boyfriend to become famous but later she regrets it and tries to get him back.

>a manga where the girl dumps/rejects/cheats on a guy due to her popularity but she regrets it and well you get it



oh and if you could can you name some where there is an UNPOPULAR BOY with a POPULAR GIRL girl can be idol, actress, etc. i know this is basically the same as what i asked for but this doesnt need to have the girl dumping the guy.

Thanks in advance guys

I believe Love Lucky would fulfill the second requirement. Its the only one I can think of right now though.

Well most of the mangas I know are more geared to males since I don't have any interest in shoujos. Also, they mainly only fulfill the second request (more or less). Personally, I like the seinen series better because it doesn't beat around the bush as much as shounen series. Here's what I can remember off the top of my head:

Seinen - Contains hefty amount of nudity and sex scenes
Nozoki Ana - happens in the protagonist's first relationship
Love Junkies - happens in first relationship, but doesn't reveal til a far bit in

Shounen - Some ecchi here and there
GE (aka: Good Ending) - Series can get annoying, and I dropped it halfway, but it has what you are looking for.
Unbalance X 2 - Happens a couple of chapters near the end of the series
Kimi No Iru Machi - Pretty good at first... but it's getting boring as the author is throwing out chapters with no real plot developments currently.

koisome momiji
I's at the very end anyway
I'll try think of more but take a look at my lists if you want more
