paraphrase:The absence of you brings sadness that still lingers in my heart. Even though time has passed, the pain of losing you persists. Your memory stays with me, and I continue to long for you. When you left, a part of me went away as well, and even though it's been years, it still feels fresh in my mind. I sincerely miss you, my dear sister.
