Just Watch the Target Break Character!

Loving someone doesn't mean they love you too; But for the sake of the one you love, you have no choice; I love you just as you love me; I hate you just as you hate me; Nothing happens without a reason~ But... Hey! He's only here to do a mission, so why does his mission target seem to be acting so strangely? And he's only approaching his target to complete the mission, so when did the plot go off course? This story is also known as I'll Protect My Big Sis to the Death! and My Mission Targets Never Follow the Script! Warnings: 1. The protagonist is on the receiving end. The protagonist's worldview is a little warped (that doesn't mean the author's is! I think mine is pretty normal?). 2. The big sisters are different in each world, and the worlds aren't connected. 3. The main couple are unwaveringly devoted to each other; the side couple may not be~ Hope you enjoy reading, everyone.
