Park Chanyeol has an ability to never forget a single moment in his life— both the good and the bad. When he meets Byun Baekhyun, a rebellious hapkido student who happened to be his new neighbour, everything begins to change. Together they uncover a mystery, create unusual memories and fall in love for the first time. 

If we’re in each other’s dreams, we can be together all the time. Sometimes, reaching out and taking someone's hand is the beginning of a journey.
