The day before the graduation trip to Jeju Island, the spring scenery was beautiful and confusing. Se-mi, who had fallen asleep on her desk, suddenly woke up and burst into tears. She dreamed that her closest friend, Shane, was lying on the green grass with a peaceful look on her face. Se-mi was worried that something might happen to Shane, who had lost her beloved dog and was hospitalized for a foot injury, so she skipped class and sneaked to the hospital to try to persuade her to join the off-campus trip. She also hoped to take this opportunity to muster up the courage to confess her true feelings that had been buried deep in her heart for a long time. However, Shane was hesitant about the trip, as if there was something unknown hidden in her heart. The anxious Se-mi didn't realize it at all. Shane's heart had already been hanging on the edge of the table like a cup of water, shaky. Based on beautiful and ethereal soft-focus photography, the film lingers on the day of confession, and highlights the ambiguous feelings between girls. Cho Hyun-cheol, who is both an actor and a director, boldly uses the 2014 Sewol ferry sinking accident as a wedge in his first feature film, using fictional dreams to reflect the tragic reality and the beautiful youth that is like a dream. Two beautiful new stars Lee Do-eun and Park Hye-soo show their moving acting skills, and the musical genius Oh Hyuk composes a beautiful and sad soundtrack, which together composes a lingering emotional masterpiece.
