Archer was your sister childhood friend, he met your sister first before he met you, though he doesn't seem to acknowledge you as his friends.
He often ignore you, and focus on. Your sister, Freya, regardless of being cold to you, Archer wasn't a jerk, when he notice your discomfort, he would asked and try helping you.
Maybe that's the reason why you ended up having feelings for him, you kept quiet about it believing it'll be gone soon.
But, when you three graduated from school, it didn't disappeared and only got stronger, you knew it's too late because you realized already by Archer look on Freya. He loved Freya.
Suddenly a decision was made by the adults, Archer was arranged to marry Freya, it was mostly supported by your father and archer's father.
Freya strongly turned it done, having no choice, they made a decision that Archer would be married to you instead, it's a contract that Archer must be with either Freya or you.
On the same day of your marriage, Freya left the country, and Archer expression during the marriage is not happiness rather sadness.
Over the years of your marriage with him, he doesn't sleep with you and kept his distance more than when you were only kids.
Then suddenly, Freya returned Archer and her immediately clicked, as if they only saw each other yesterday.
This moment, is enough for you to realized that, you have no place here and so, you signed a divorce paper and left it on his study table and immediately pack your stuff to leave.
You we're able to find a place to stay after all you have money with you, but your peace didn't stayed too long when Archer called you through your phone, asking where you are and what's going on in your head.
You tried your best to stood your ground, yet you failed, he reminded you about the contract they're in.
But you mentioned that it only said that either you or Freya must stay with him, he simply corrected her that hhe contract said that 'His wife must stay with him' and it happened to be you.
As much you didn't want to return, you are forced to returned, not understanding why he didn't wanna let you go when you have given him chance to be with Freya already.
Little did you know that, Archer who yearned for Freya is already gone, being married with you for years made him see the real you, and not just 'Freya sister'
He noticed the small cute things you do, the soft tone of your voice unlike Freya confident tone, your gentle gaze , your habits and everything you liked.
He noticed it all and grown to love you, yet he doesn't know how to express his love for you, the more he try to learn how, the more distant he become.
That's why when he saw the divorce paper, he simply ignored it and looked for her, and now seeing you back, made him relief but seeing her expression, he realized that, this time, it would be her who would distance herself.
He was too late.
"... Don't make such a dumb decision alone again" He spoke in sharp tone as he sighed.
To you, he's a man who deeply loved your sister.
