"Nostalgia beer" allows you to have a little conversation with your past self. A girl who can't be herself in front of her younger boyfriend, an advertising salesman who tries too hard and ends up spinning his wheels, a university student who always chooses the safe path and can't take the first step towards his dreams, an office lady who is ashamed of herself for eating convenience store food every day due to her busy work schedule... Adults who work hard every day despite their doubts find a chance to find their "precious selves" after accidentally getting their hands on a "beer". Even adults have a lot of doubts. The first in a refreshing omnibus collection that will touch your heart!
