Through Italki I’ve messaged with someone who recommended the 만화 called 신부 이야기. It was originally published in Japanese, but the translation to Korean is quite nice.
It’s set in the 19th century around the Caspian Sea, and the story follows 20 year old bride 아미르 and her 12 year old child groom 카르르크. Due to the age difference they are considered a bit of an odd pairing… 아미르 is a quite active young lady who has an outgoing personality and knows her way around a bow and arrows so it should be interesting to see how the relationship with her new family unfolds.
The drawings are absolutely beautiful so if in need of some new 만화 inspiration, you might want to check it out.
