Lee donghae  who just entered college. He was the not so popular guy with almost no friends. Until he fell in love with the most popular girl in the college im yoona... Every boy was after yoona... She hadn't even ever noticed him but he was always there trying to start a conversation... Eventually when time passed donghae became popular and became friends with yoona. Soon they were best friends yoona always shared her sorrow with him and they were always on their phone talking. Donghae  thought that yoona also fell in love with him so one day he decided to tell her his feelings. He sent yoona  a message asking her to come meet him in the park...yoona came and they started to talk

donghae: Hi!

yoona: Hi! What happened? Why did you call me?

donghae: I have something important to tell you...

yoona: Go on..

donghae: Well since I first saw you I fell in love with you! I love you more than anything, you are my everything, I love you so much that I would take a bullet for you, I...

yoona  interrupted him,

yoona: Errrrmm.. Everything you said is very touching.. But sorry I do not feel the same for you.. I'm sorry..

A tear drop fell from donghae's eyes. And there was a moment of silence....

donghae: Okay I understand... Can we stay best friends though?

yoona: You know how I am.. I won't be able to consider you the same anymore.. I've gotta go, bye.. It would be better if you could forget me and please don't even call me, I won't reply..

Saying this yoona  left the park donghae was there alone in his grief.... For the next four days donghae did not go to college... And when he came back he was silent.. Not even joking around as he used to.... Everyone asked him what was the matter but he said all kind of lies....

A few weeks went by and by coincidence donghae met yoona in a music shop...yoona did not look at donghae but donghae was constantly peeking over to see a glimpse of yoona...

Suddenly an armed man entered the music shop and asked that everyone handed in their phone and everyone did as he asked apart from yoona, she though that her phone was on silent and that she could just call the cops when the robber was not looking but she was wrong...... Everything was going fine just before her phone rang... The robber became mad and aimed at yoona...

Just before he could fire, donghae came in between the robber and yoona  and a second before he got shot she said to yoona;"I told you I would take a bullet for you" and the bullet pierced his heart... donghae died on the spot......
