The poster is a visual reinterpretation of the song "Water Park" by singer Wonderland.The character, who is in a crush, looks sad at repeated mistakes and behavior that does not turn out to be like a heart. It feels like a sinking feeling because of a mistake in a swimming pool.I compared the speaker's sad story to the self-portrait. 
The poster was exhibited at the 2nd Bigriver Poster Festival. This festival is a college song system with pure passion in the 1970s and 1980s.It is an exhibition where contemporary designers and bands gather together to solve their passion in their respective ways.
