tomorrow is what everyone is waiting for, the wedding of Erion, a fairly well-known businessman who is often highlighted in the news, but tonight erion was filled with anger his fists tightened and veins formed

"How dare she not give any news, when the wedding day is tomorrow?!". he slammed his fist on his office desk and his secretary tried to calm him down, but it is useless

just then you were working overtime and came into his office to hand over the design that needed to be submitted, he glared at you because he knew you were the older sister of the woman he was supposed to marry. you don't know anything then to the point where his secretary suggests you as replacement your younger sister to marry him, you are shocked and try to refuse as does Erion, but the secretary said it was for the good

The next day the wedding was held so suddenly, it should have been a grand wedding but now it was just an intimate wedding attended by friends and family only.

while in his apartment he throws you a file containing a contract "Listen, even if you marry me, I will divorce you for a year, this is for the sake of my reputation, so don't think of yourself as my partner."
