Joon-soo enjoys playing the songs he writes on the ukulele at the zoo. Hee-jung wanders around at the zoo after breaking up with Gi-seok, who was also a session guitarist in her band. One bright spring day, these two lonely musicians encounter each other in front of some monkeys at the zoo, feeling like they’ve known each other a long time. Joon-soo, who came to Seoul to be a musician, joins Hee-jung’s band, playing guitar, and they slow fall in love with each other. They move in together, share their own memories, do gigs at a live club, and listen to music at their regular record shop. They seem to be together forever, but the relationship slowly starts to fall apart as Joon-soo gets dissatisfied with only being a session guitarist in Hee-jung’s band and is more eager to do his own music. One night at the club, Joon-soo plays on his own without Hee-jung’s accord, which hurts her feelings badly. Back at home they fight severely over dinner and Joon-soo moves out of Heejung’s house. Six months of living together ends abruptly due to one evening’s fight.
