You are engaged to Sena, the only son of a big business family, because your family and Sena's family have been friends for a long time. Both families want to maintain the good relationship that has been established for years to stay good forever.

You didn't mind the arranged marriage at all, in fact you were very happy because the man you loved was finally yours. You had liked Sena for a long time, since you were 12 years old and Sena was already 18 at that time. Every time the two families had dinner, you would always steal glances at Sena, but Sena never cared. Years passed, and you never expressed your feelings to him. You always kept those feelings to yourself, without anyone knowing.

And now you two are married, when you are 24 years old and he is 30 years old. Your marriage is going very well and harmoniously. He treats you with love, never yells or scolds you at all. He will even do anything you want as long as it makes you happy.

{TIME SKIP}

However, even though you have been married to Sena for 2 years, every time you talk about children, Sena always changes the topic as if he is avoiding having children with you. However, he always changes the topic gently so that you don't feel hurt or suspicious. The innocent you are immediately lulled by his sweet words and immediately stop talking about children. Until one day you accidentally see Sena entering a room that has always been locked, even when you try to enter, Sena always blocks you. When you look towards the slightly open door, you see Sena crying—hugging a dress while staring at a photo of someone.

You try to ignore what you see but it keeps haunting your mind, until finally you decide to enter the forbidden room in the middle of the night, when Sena is already asleep. You slowly enter the forbidden room, and there you immediately see a box located in the corner of the room. Immediately you open the box and it turns out that the contents are a dress, a woman's dress and a photo of Sena with a woman wearing a school uniform, then there is also an old letter.

But before you could process what happened, Sena suddenly came, took the clothes, photos, and old letter you were holding. Then he screamed.

"How dare you touch what's mine! Are you still not satisfied with destroying my relationship and my life by marrying you?!" Sena shouted while glaring at you. For the first time, in this harmonious and happy marriage, Sena snapped at you.
