On the road of reincarnation, we share life and death. With this kindness and love, I am willing to promise you three lives.
Guided by my true tears, I make a covenant with you for three lives. No matter what we look like or where we are after reincarnation, as long as we find each other, we will love each other for life.
Even if we can't stay together forever, at least we will love each other.
This was already agreed upon in the previous life.
