Youth has no regrets, and a glance lasts for thousands of years. That meeting became an eternal longing, despite changes in the world and multiple obstacles, the promise between each other cannot be forgotten. Leaving is not giving up, but for a better start; missing is not missing, but for better encounters; letting go is not forgetting, but for better expectations. The past has become eternity and will not change. The future is still unknown, but we can give it a try, and there will be no regrets even if we are attracted by moths to the flame.
