"Empty Space" by Eddy Kim is a song about loneliness and longing for someone who has left. The lyrics convey the feeling of emptiness and sadness that one experiences after a breakup or separation. The song starts by reflecting on the past, with the lines "Geuttaen mollanna bwa oerowotdan sasireul" (Back then, I didn't know the truth of feeling lonely) and "Jogeum jinamyeon samuchil georaneun geol" (I thought it would pass if a little time went by). The protagonist realizes now that they were unaware of how lonely they would feel after the person they loved left. The chorus emphasizes the emptiness and pain the protagonist feels, with the lines "Empty space gumeongi nabeoryeo" (Empty space, a hole that's formed) and "Keojyeoman ganeun apeum" (The pain that keeps growing). The protagonist pleads for the person they lost to come back to them, expressing their longing and desire to fill the empty space in their heart. As the song continues, it expresses the inability to fill this empty space with anything else. The lines "Mueoseul chaeul sudo mekkul sudo" (I can't fill it with anything, I can't erase it) and "Eomneun gaseum han kyeone bin gonggan" (An empty space in my heart that can't be filled) depict the frustration and helplessness the protagonist feels. In the second verse, the lyrics mention the absence of even bittersweet emotions, with the lines "Aeseokhan gamjeongmajeo eobseo ijen" (Even bittersweet feelings are now gone) and "Yaksokhan sarangmajeo deungeul dollil ttae" (When even promised love is turned away). It emphasizes how the protagonist's heart has become empty and deprived of any form of emotional fulfillment. The chorus repeats, reiterating the intense pain and loneliness the protagonist experiences. The lines "Empty space honjaneun dojeohi" (Empty space, I can't bear being alone) and "Meul su eomneun neukkim" (The feeling that can't be healed) emphasize the desperation and longing for the person to return. Overall, "Empty Space" explores the emotions of emptiness, loneliness, and longing after the end of a relationship. The lyrics depict the protagonist's yearning for the person they have lost and their struggle to fill the void in their heart.
