Seven-year-old Yui Yuan and thirteen-year-old Luo Feng first met in a sea of cherry blossoms. "This cherry blossom is called Beauty Cherry. It blooms once a year and has a long flowering period. It can ripple in the scorching sun and stand upright in the wind and frost. Judging from your clothes, you must be a girl from the south. Beauty Sakura often grows in the north. You are a perfect match for this flower at such a long distance. My name is Luo Feng, what is your name." "Yuan Yuan." "You will marry me in the future, and I will take you with me. Let's go see the most beautiful sea of cherry blossoms, okay." "Okay, let's settle it. Dad said that I would give you a token of longevity, but it is the most important thing on my body. Don't lose it." "Okay, when this sea of flowers blooms again, it will be when I marry you. You are the flower, and I am the thorn. I will protect you with my life."
Life after life, take the lock as your faith and the flower as your witness. If there is any disobedience, use your life to offset it.
