Taeyang is a 15-year-old boy that lives apart from his parents that kicked him out of the house, out of hatred towards Taeyang. He was young and innocent, he doesn't know anyone until he met someone with the same fate as his, Kwon Ji Young (G-Dragon). G-Dragon then introduced Taeyang to other 3 friends that also has the same fate as his and all of them were friends ever since. They grew up and lived their life together through thick and thin. Now one day, at Taeyang's school while he was on the way to the library to meet his friends, he bumped into a mysterious girl. She looked so beautiful to Taeyang's eyes. As time goes by, he found out that the girl was actually someone he knew and he loved.
