:Love, no matter how genuine it is or how beautiful it may be, can still hurt both people when being together is destined to cause pain. Knowing this, Paje chooses to let go without looking back, because he is afraid that if there is another life, he might choose her again. Out of love, he hardens his heart and walks away.
As for the one who misses and the one who is missed, there is no clear answer as to who suffers more. But in the next 999 lifetimes, Paje, who becomes a great warrior, will still have to painfully turn his back on the people he loves.
In the end, whether love ends in possession or separation, what truly matters is how deeply and sincerely two people have loved each other. That is why Chapter 4 leaves us with a question: Do we have the same courage as Paje to let go of someone we truly love?
