In that life, who could bear the ungratefulness of killing his father and his enemy? Pointing your sword at that person, you can't feel any pain in your heart.
In this life, the tragedy of annihilation will happen again, and that person is back. He pointed the sword at himself, feeling no pain in his heart.
Some love, like a reflection in water, disappears with a wave of your hand, but will return soon.
Stop kidding yourself and just let it be.
