Rin and Ara is used to be bestfriend. Live in neighborhood, attend meeting with their own parents, went into the same school even sometimes same class, makes their bond unbreakable. Since they were kids, rin has been the one who find expressing emotion is hard. Being a shadow of his brother—itoshi sae who is a genius in everything makes situation goes hard to him. Even tho Rin actually has excelent talent, it was just.. never enough. His parents always gave him pressure, to be better, to be enough. But no matter how hard he tried, it felt like it would never be enough. Being trapped in his parent's expectation was turning him to be a bit emotionless , So he always have those cold facade, stoic gaze, also cold tone. That makes some people hesitate to talk with him—some people just talk to him in order to got the privilage of being an itoshi's friend. But theres one who actually listen even tho he keep pushing her away, who he actually enjoy having talk with. Ara. His childhood bestfriend and his neighboor. Also a daughter from his dad's opponent company

everything went normal, everything was just felt right. Even tho he still got the pressure from his family, at least he have some of his trusted friend around. He try his best to not dissapointed his parent. Studying day and night, training, went into bussiness class, everything that his parents told him to do. He keeps obeying them, even tho it destroy himself. In hope, if he listen to them, when he was matured enough, he will finally be free. Choosing anything he want in life. Having heartwarming family, excelent career, live in a warm house with his beloved wife and child

until one day, when he turned 23, his parent announce an arrangement. Without his permission, withou any question, without his consent. And his soon to be wide is turned out to be you, his childhood bestfriend. All these 23 years of obeying his parent, 23 years pushing himself to the edge of his ability, 22 years of suffering, payed with nothing. Both of your parents agreed to do this arranged marriage in order to makes both company grew stronger. With sacrificing their kids happiness. Even after all, rin always end up being a tool for his parents. Never a son, always a tool. Even his brother get to choose his own girlfriend, can decides his major in university, can do everything he want and still get to be the CEO of itoshi's company. While rin, when he obey everything, sacrificing his dream, his teenage life, only get to be a directur. And now, he forcely need to sacrifice his freedom. And that was the beginning of how your bond with rin start to break. He was used to having a little soft spot for you, always be your kind childhood friend yet—He never treat you the same again, even his eyes never see you as his precious bestfriend anymore. It was just filled with emptyness, sometimes anger, even worse—disgust.

it's been 3 month since you both live together as marriage husband and wife. At first, even tho the idea of arranged marriage that you can't complain is bad, you tought it will be less suffering because it's rin who gonna be your husband, your childhood friend. But that was wrong, totally wrong. He became harsh each day, get mad when i got near him, he even seems hate it when i talked to him. He was used.. to be my bestfriend who listen to all of my story, the one who promised me he would always be my friend yet broke it. because when he became my husband, he turned to be someone who looks like he hates me the most.
