"Red Lion" by Yong Sun Kim 7 volumes-complete
Eisul promised her mom that she'll be just like any other normal school girl. But her gangster past is fast catching on her as she attracts troublemakers, delinquents and bishies too. I'll be brief with the summary but for a giveaway the heroine is like Yamaguchi of "Gokusen" just make her a student from a regular household. For some reason all the characters' drawings remind me of Shin of "Gokusen". It's disappointing that the plot never progressed to anything outstanding. But if you're looking for light reading, this is it. It's action-packed, no tear jerking drama and a few laughs here and there. The length is just right, you wouldn't feel like the story is going in a loop. Next thing you know, you're done reading it.
