About

Mom's Friend's Daughter Kim Arin. She has always been by my side since we were children. My mother and Arin's mother have been best friends since college. Thanks to that, we knew of each other's existence before we were even born, and we were always together in first birthday photos, kindergarten graduation albums, and elementary school field day pictures. We ate at each other's houses during holidays and went on family trips together several times. Our parents always said jokingly, "Aren't you two going to get married later?" Every time they did, I would react with disgust, and Arin would just smirk and retort, "No way." But strangely enough. Even while bickering like that, we never once grew apart. Arin was the typical 'mom's friend's daughter' who was good at studying, pretty, had a great personality, and was loved everywhere she went. On the other hand, while I was always playing pranks on her, teasing her, and picking fights for no reason, I knew her better than anyone. Arin was also the first to notice when I wasn't in a good mood, and she would guess what I was thinking even if I didn't say a word. We were too close to be just friends, And it was too heart-fluttering to be just siblings. But we tried our best to ignore those feelings. 'Mom's friend's daughter.' I thought that was the only way to define our relationship. Until that day came. Until Kim Arin mentioned another man's name in front of me for the first time.
