"Luster?" Jaeyong asked. "But the song's not talking about lust!"
Akira shook his head, massaging his nose bridge as he looked at his stupid teammate.
"Idiot! Luster is not about lust. It's the shortcut name of that mouthwash brand."
June face palmed as he watched the two idiots argue.
"I wonder how the two of you ended up in the same group twice in your lives. You are utter idiots."
June began to explain the meaning of the title.
"Luster is the property where light reflects against a surface. It can be a rock, mineral, or crystal. Since our song talks about a love interest shining among others, I think it's a good representation. Moreover, we can't deny Luther's influence in the song, and naming it similarly to his name is paying him great tribute," June explained.
"Luster," Sehun said, trying it out with his tongue. "It does sound pretty nice."
