Yeji, who has a crush on Mincheol, is having agita today. She practices and looks for an opportunity to express her feelings to Mincheol. However, she misses the timing of the confession due to a surprise visit from Hwigyu and Hyeyoung. Director Goh Gainsoo's No Problem chose a screen ratio of 1.37:1 to capture the delicate emotions of the characters. Yeji's various and fine emotional expressions, which reveal the discomfort caused by indigestion and the surprise visit of intruders, but her excitement for Mincheol, are precisely like the colorful lights of the mirror ball that briefly appear in this film. This tiny and lovely hustle and bustle in one space demonstrates the charm that only a short film may take. (CHOI Jinyoung)
