A BL fiction about how a boy entered the imperial harem to replace his sister and end up having the Emperor fall for him

Maybe I am weird or maybe I have a wild imagination, but a storyline kept popping up in my mind and I HAD to write it out. Very much like a KDrama, "When Toronto Came For Seoul" is a story of forbidden love. Kpop stans all know how a dating scandal can reek havoc on the career of a kpop star. Secrecy and threats wear down on Dani as she maintains a private relationship with Min Jun (Jun. K of 2pm) as if that wasn't difficult enough Canadian rap super star Drake has his eyes on making her his... while JYP is up to no good.
