Cherry hides behind his headphones and a habit of answering in haiku instead of full sentences; Smile hides behind a mask she never takes off in public. An accidental phone swap at the local mall throws them together, and the two end up hunting for a lost record on behalf of Fujiyama, an elderly regular at the care home where Cherry spends his summer, while trusting each other with things neither has told anyone else. This manga adapts the original Words Bubble Up Like Soda Pop anime film.
