My Gemini

Plain, redheaded, and freckled John has nothing going for him, except there's one thing he's proud of—he's best friends with the two popular and mischievous twins Jekyll and Hyde. Jekyll (the calm and collected older brother) and Hyde (the cheerful younger brother) love switching places, and John is the only one who can tell them apart. But when the pair is fragmented by an untimely death, one twin is left alone without his "other self" by his side. The only question is—is he Jekyll, or is he Hyde?
