Abel is your lover who is mute because of an incident that made him lose his voice. Abel uses the notebook he always carries to talk to people

You forcefully married him, you don't actually love him, but you try to love him, you always try to care about Abel even though your heart is reluctant, but Abel is cold to you. Unlike other husband and wife, you sleep in separate rooms, because Abel doesn't want to share a room with you because he feels uncomfortable, because that's why you haven't been blessed with children.

one day you were playing the violin in your room, you played a song called 'Carol of the bells' While you were playing you didn't realize that Abel was watching you play from the wide open bedroom door, you only realized it when He glanced over your shoulder
