Hey There, After this past Month looking at almost everything i can.. I've been looking for some specific types of Romance.

1. Higher Class, But doesn't start out that way. Ex. Girl is raised by single Mother/Father takes a job/Finds out that other Parent is High Class person. AFTER She falls in love with that Parents other Son.

So in order of Events:
Poor Person
Meets Unknown Parent's Son
Falls in love
Finds out She's Related
Complications Occur.

I would Prefer that the Sibling would then give up and she finds someone new, Because it almost never happens. But The ending getting Together is OK too. Or the Falling in love with Sibling can be Ommited. Or something along the lines of a hidden past. Unknown one etc.

Ex: Grand Sun

Later on, Asashi finds out her past etc.

Somewhat: Shinshi Doumei Cross

2. A school life Romance with a friend Helping out another Friend to get another Guy, Who happens to be in love with someone else/ Or unrequited Love, the Friend, If happens to be the opposite Sex, Can't get Romantically involved and Girl/Guy Gets Original Crush. Or a Love square of: Girl #1 -> Guy #2 -> Girl #2 -> Guy #1 -> Girl #1. Guy/Girl #1 and Guy/Girl #2 help each other to get Respective Girls/Guys.

Ex. Much like the Beggining of ToraDora!, Beggining of Dou Danjo!? ->

But the Endings Have them End up with their respective Crushes Instead.

Sorry About Requesting such Exclusive Manga's.

Preferably Shoujo, can be others. No Yaoi/Yuri/Hentai Please.
Thanks in Advance!
