This is a Korean Manhwa.

{From Tarot Cafe}
"Why is my life so messed up?!"
Haeun has a step brother that's a gang leader
and she gets blamed for everything he does.
When her brother makes it so that she is late for class,
she has a strange encounter-
the encounter that makes her a housemaid for the rest of the year.
Haeun, who hasn't even had her first kiss yet, decides to take revenge.
But when she finally kisses someone -and it isn't pleasant- what will happen?
