How far can one's heart manage a heart break? How far does one have to get to realise the true meaning of love? 

Summer, Ha Yeoreum, who suffers a heart break from her ex-boyfriend's betrayal. 
Do Kyungsoo, who doesn't know love, nor has he ever loved. 


She, lost her consiousness.
He, found her. 

How far will he lead her? How far will they stop? 
.... and when the time comes, both will not know what to expect.
