I don't know why nobody write a review for this manga. I think this is some of the best manga I have read. The girl is kind of reckless and the boy, totally gonna melt your heart!!
But, I don't think that the title suit the story. Read it to know why.
Now, the story.

It's about a girl who likes to work halfway without even try to finish it!
One day, when she's on the way to go for her entrance exam, she fell on a pile of snow. Her clothes were all dirty. She give up to go for the exam 'cause she's already late. Suddenly, an unkown boy say something to her that makes her spirit level up again!

Finally, she pass her entrance exam. She wants to meet the boy again but she only have the boy's handkerchief for a clue. She showed the handkerchiefs to her friends and they all were shocked!
What's happening?!!
