Baekhyun offers the world to Chanyeol in exchange for a little time and a fragment of his purity.

An agreement is made, but the beautiful autumn weather takes both of them away, 
giving the two an unforgettable experience that reveals some truth and sincerity,
something unattainable by other means.

Perhaps he won't ever be able to see the leaves fall and catch the sunlight, 
but I will show him what the world has to offer him regardless.
