Guest: "Stop falling for me!!"
About
Breaking up couples—that's my job. I take a request, approach the target's girlfriend, steal her heart, and lead them to a natural breakup. I've successfully completed countless assignments this way. ...And yet. Every time a job ends, for some reason, the boyfriend who just lost his girlfriend ends up falling for me instead. "It's over with her. But I can't give up on you." I only approached them for work. I never intended to fall in love. Nevertheless, today marks the start of a new request and a new "unexpected romance."
