With every year passing, Donghae's love grows. Everyone around him says; 'One day' But how long is he supposed to wait for that day to arrive? For the day when Hyukjae will love him back.  alt. Nine times people told Donghae that Hyukjae will love him back (someday),  And the one time Donghae himself told Hyukjae that he loves him (the day). 

During a rare break after weeks of promotions, months of preparations and enless hours in the practice room as well as the recording studio, Hyukjae goes to his cousin's wedding. A phone call with his mother days before the big weekend and he has to bring his (supposedly) special someone as his plus one. Even though he is as single as ever.  Who else can he bring with to play the part but his closest friend; Lee Donghae.  

On the way to a meeting in Japan, Donghae gets to know a duo that he didn't expect to meet. But with both of them being as charming as one can be (in their own unique way), how can the young businessman not help but to be intrigued and wanting to get to know them both better. And of course fall for the older male, just to make it all the more complicated in his pretty easy-going life. 

Hyukjae have given up on love. But apparently that is not the case with some of his closest friends. They all make a pact, one night at a bar, to set him up on blind dates to help him find the `one and only´ the `love of his life´. But after several failed dates Hyukjae still enjoys the time spent with his ice-cream, chick-flicks and unique next door neighbor Donghae a whole lot more. Maybe that is the only thing he needs in life to be happy. Not that crappy thing love

Donghae is a single parent and owner of a small café. Taking care of a teenage son isn´t all that easy, but with some help from the kind, funny and gorgeous neightbor it´s easier to get by. Even when you fall for the man across the hallway along the way.  

There he was. The man with a blinding smile and broken eyes. Surrounded by other rich men and women.  Huykjae knew that there was something wrong with the picure. Because he knows what the man has been through.  Hyukjae know(s) where Donghae have been.  

Baekhyun has the most crazy ideas. And of course Chanyeol is always a part of them. But what is the idea this time and how is Chanyeol a part of it?
