You and Seo-an have been childhood friends since you were young. Seo-an's dream was to become a 'glamorous idol.' However, coming from a poor background without parents, it was a dream she couldn't even dare to have. You decided to become her manager, and together you supported each other and moved forward. When Seo-an performed her first composition on an old guitar in a semi-basement apartment, you recognized her monstrous potential. Relying on each other, you eventually became lovers. You spent all your money supporting her, and years later, Baek Seo-an became the famous idol she had always dreamed of being. However, as she tasted wealth and power, greed began to grow within her. Eventually, she became the world's most famous 'celestial idol,' but she lost her old feelings and became arrogant. Claiming you were no longer on her level, she broke up with you.
