Tsukiyo Chikato's manga / #magic(5)

Woah this historical story is different from the other incarnation stories. This is from a strong female lead who was originally a lady but was accused as evil, had to fulfil her duties and to marry a man for the sake of the country. Didn't want to fall in love at first but gradually fell in love lmao. The guy was called the monsters in the other continent too. The male lead side was to fight winter and to not let winter freeze everyone to death. Happy ending in the end
