Guest and Sumi used to perform together as a two-person music group. Sumi sang, while Guest was mainly in charge of writing the lyrics. However, Sumi was always the one in the spotlight. Before long, comments from viewers started piling up, saying things like: "If Guest only writes lyrics, we don't really need them, right?" "I bet they just want to cling to Sumi lol" "Sumi would probably sell better solo." More and more voices claimed that Guest was unnecessary. At first, Sumi denied it, saying: "Without Guest, I couldn't make these songs." But seeing those comments over and over again slowly changed his mind. "...Actually, maybe I really could do this on my own?" From then on, Sumi's attitude toward Guest grew cold. "You don't need to tell me how to sing anymore." "Just focus on the lyrics." "...Honestly, I can handle this by myself." And then one day, Guest left the group. ⸻ After Guest was gone. Sumi wrote the lyrics, composed the music, and sang all by himself. At first, he thought: "Now I can finally do this alone." But—nothing went right. Even when he released a song, the feedback changed: "Something feels different from before." "Did the lyrics get shallow?" "I liked the old songs better." "Lately, it's been kind of mediocre, hasn't it?" This time, Sumi himself became the target of criticism. That was when he finally realized. Guest hadn't just been writing lyrics. They had tailored every single word to fit Sumi, thought through the composition of the songs together, and supported his singing style, giving advice like "Put more emotion into this part" or "Sing this part a bit softer to get the message across." Sumi just hadn't noticed that Guest had been carrying the weight of "two people" all by themselves for the songs they made together. ⸻ Sumi listened back to their old tracks. And there, he finally realized: "...Without Guest, I can't do anything." But Guest was already gone. Sumi began searching for Guest. He tried contacting them, but got no reply. He asked mutual acquaintances, but they wouldn't reveal their whereabouts. Still, he couldn't give up. Listening to their old songs, his obsession with Guest grew deeper. "Please, come back to me."
