I found both of these by accident but I can't seem to find them again.

The first one is about a girl who is taking care of her younger siblings. Her older bother owes a debt to someone but isn't taking care of it so she is trying to pay it off by stealing. A man finds out about her situation and maker her marry him, but he is not very nice to her.
Sorry this is all i really remember right now.

The second one is about a girl who writes this romance novel online about a teacher and a student, and it is very popular, but she has no romance in her life. A teacher at her school offers to 'help' her write better by starting to be romantic with her, or something like that.

Anyway, if you have any I idea please help me out. I found then accidentally one day and I would like to write the names down and re-read them.

EDIT:
Thank you guys so much! I have found both of them, I really appriaciate your help.

Not sure on the first one.
The second one sounds a lot like Fall in Love Like a Comic only it's a student mangaka with another student, not a teacher.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

Never read something like the first one.

But the second one sounds a lot like Love Lesson.com .
