Luhan is blind.

Sehun has a brain cancer.

They met in a hospital.

All begins with Sehun hearing the beautiful melody of a piano next door and went to find it. Start from that time, they'll learn how to love someone.

Luhan is almost desperate. He hates life. He hates the reality that the world is really unfair. He wants to see the blue sky, the reasons why people are laughing, the green grass, the face of people around him. He wants to see the world.

Until Oh Sehun came and change everything. He taught Luhan the beauty of life, and for the first time, love.

Now he doesn't want to see anything as long as Sehun is there with him, he believes everything will be just fine.

"I can't see the purpose of me living in this world before I met you. I always saw darkness, like I'm trapped into a world's hell. But the day I heard your voice and sensed your presence, I saw brightness for the first time."

"I don't know what's gotten into me that day until I approach you, sitting in front of the piano, fingers dancing elegantly playing beautiful melodies. Since that time, I began to know what love is."
