One day, Buck took Y/n for a romantic walk by the beach. As they walked hand in hand, Buck knelt down on one knee and revealed a ring, asking Y/n to be his wife. Y/n was ecstatic and said yes without any hesitation. She had always known that Buck was the one who would complete her life, and now, they were going to spend the rest of their lives together. They hugged each other tightly, feeling overwhelmed with joy and excitement.
