Byun Baekhyun, a Child Prodigy with an IQ of 287 and Park Chanyeol (let's not mention his two digit IQ) used to be neighbours until some suited white men showed up at the doorstep of the Byun's one fine day and took Baekhyun with them to a 'school of gifted' in the West. Chanyeol couldn't have been happier to see the biggest curse of his life finally leave. 

But no one told him, ten years later, that Byun Baekhyun was coming back to town. 

Living diagonally opposite to each other and Chanyeol not being able to stand the sight of Baekhyun, only heaven knows where this would head.
