[Voice Lover] [Online Romance to Real-Life Meeting] [Sweet Campus Romance] [Both Unmask Each Other]
Su Wantang has a secret: she has a perfect memory for voices, and every person's voice has its own color in her mind. Her online boyfriend of six years, Y, is a "sunset sea," deep-sea blue wrapped in sunset orange. His is the most beautiful voice she has ever heard.
Jiang Yubai has a secret too: the aloof, taciturn computer science genius at A University, admired as an untouchable flower, is actually Y, a top-tier star voice actor across the internet. His online girlfriend of six years, "Little Moon," is somewhere on the other side of the internet, and he doesn't even know her name.
Then, one late night, Su Wantang goes to her roommate's older brother's home to pick something up. Through a crack in the door, she hears that familiar sunset sea.
The voice she has fallen asleep listening to every night for six years is coming from her roommate's brother's room.
Later, at an esports club fun match, she instinctively uses the signature moves of "Moonshadow," her ace game booster. In the darkness of an escape room, she blurts out, "Brother Y!" In the cafeteria, she deliberately repeats his catchphrase, "It's such a nice day today"...
He wears a cold, gray-blue mask, but she keeps making him lose his composure.
"Senior, the color of your voice is exactly the same as my boyfriend's."
"...Has your boyfriend ever told you he's been waiting six years for this day?"
The Y-god who's been in an online romance for six years × Little Moon, who has a perfect memory for voices. When deep-sea blue meets sunset orange, which of them will be the first to surrender in this romance where both uncover each other's identities?
