Alicia's favorite song is hard for her to pick, she really likes "Can't Take My Eyes Off of You" by Frankie Valley and The Four Seasons, "Fly Me Too The Moon" by Frank Sinatra, and "I'll Never Not Love You" by Michael Buble.
The song she would associate with Kattar would probably be "Naked" by James Arthur.

Kattar's favorite song is "Let You Down" by SWS. But he would associate several songs with Alicia. "Lose it All" by Sam Tompkins would be one, but he's never heard it, so out of songs he has heard ""Still Into You" and "The Exception" by Paramore, as well as "If I'm James Dean You're Audrey Hepburn."
Tbh, Jinwoo doesn't listen to much music, but he likes some really chill songs he's heard like "Dudududu" by Jeong Sewoon and "Concrete" by Cheeze. He never ever speaks Korean, but he does understand it completely.
He also relates really strongly to "Waving Through a Window."
James Arthur is much too intense for him, but he would associate the song "Free Falling" with Kimberly if he could manage to listen to it. As for songs he has heard, maybe just that Keshi line "What can I do/ I thought you were an angel/ I lost myself when I caught sight of you."
And for Kimberly, her favorite song is "Choker" by TOP, but the song she would probably associate with Jinwoo would be "From the Start" by Laufey or "Only Us" from Dear Evan Hansen (she loves musicals.)
