Can you (the reader) imagine before, you found a new friend named Yang Seungho, a cruel, rude, careless and little arrogant boy but handsome and charismatic one?

You (the reader) currently lived in Australia with your mom, while your dad stayed in Korea alone. Yeah, they were already divorced when you were still a little girl. One day, your mom got into an accident and passed away. In her letter for you, as her will, she told you to go back to your dad's place because he needed you so much. Well, you followed what she wanted and you finally returned to Korea alone with anything you have. 

On first day of school, you didn't get accepted well and either Seungho did. Because of that fact, you made friends with him, so you were his only best friend in Korea and so did you.

Your friendship grew deeper and closer and something you don't know, that you two became dependent on each other. He taught you many ways to enjoy life and you gave him a comfortable feeling that he looked for but he became so protective of you more than just a friend. You suddenly thought, that's not a good friendship since he's too much controlled your life, built a wall around you two so there's nobody around you could annoy you. Seungho has changed a lot...

What will you do if there's another guy, who offered a nice and normal friendship to you? Will you leave Seungho or you will ignore the offer and prefer Seungho to him? You never know the answer till Seungho told you the truth...
