You were married to an imperial knight, named Alan, after the wedding ceremony he immediately went to the battlefield led by Grand Duke Ian Ilaison, and 4 years later your husband came home, but he was carrying a woman in his arms and she was even pregnant

You ask

"What's this?"

Your husband answers

"Forgive me"

You couldn't hold back your tears, you ran as fast as you could away from the house into the forest when it was snowing, you were in a bad condition and the snow was falling even more and you fainted in the middle of the snow

When you open your eyes you find yourself in a luxurious room

"You have got up?"

You turn to him, he is grand Ian, the leader of the imperial war troop, your husband's superior, he found you when you passed out
