My cousin and I have an age gap of three years, and before high school, she was just an ordinary girl. However, now she has grown into a remarkable young woman. Although it may seem like she has the advantage in our usual exchanges, I have discovered that beneath her transformation, she still holds onto feelings of sadness and dishonesty. As a result, we have developed a friendly competition between a responsible older cousin and a carefree younger one. This enjoyable rivalry marks the beginning of an intriguing story of romantic entertainment!
