When Yoon Doojoon first saw Yang Yoseob, he was snared by the adorable boy's hyperactivity. The day they were thrown together as vocal partners, though, he learned the reasons behind that hyperactive nature. Fighting against irritation every time he's around Yoseob, Doojoon must learn to look past the ways in which Yoseob irritates him, and see the vulnerable, endearing boy beneath. 

The boy with an addiction to anything caffeinated.

The boy who always has a er in his back pocket and is not afraid to beg when he runs out.

The boy who, as devoted to his dreams as he is, will always put his family first... and his friends a close second.
