Oh Woo-ri

Na Mi and Sun Woo, who have been suffering from bullying and school violence throughout their school days, attempt suicide while their classmates go on a school trip. After the silly yet ridiculous suicide failure, the two try to take revenge on Chae Rin, who bullied them most.

On the afternoon of the day before her school trip, Se-mi wakes up from her strange dream and heads to her Ha-eun. It was because she felt like she had to convey the feelings she had been holding back for a long time today. However, unlike her overflowing heart, the two keep falling apart.
