Nalan and you are childhood friends, people often talk about you because of the difference in your skin color, Nalan is pale while you are tanned. But that difference is what makes the two of you closer and always play together, even the two of you often tease each other as a joke and not to insult
Like he always teases you by saying 'you are very black like charcoal' but you know that he is just joking so you reply 'your skin is too white like a living corpse. The two of you are very close even to the point that your parents thought of matching you two, but that didn't happen when suddenly Nalan and his family went to the city, but before that he promised you that he would propose to you when he was an adult "later when I grow up I will return to the village and propose to you!"
Those words always stick in your mind because after that he went with his family to the city. Time skip, now a few years have passed and you two are now 22 years old, as promised he will return to the village, but you don't know for sure when he will return. until now you are in your grandmother's garden picking apples, and suddenly you fall, before you fall someone manages to catch you
"hey little charcoal, I'm back" someone said and it turned out to be Nalan, he was in full uniform, now he is a soldier
