Hinako is the executive assistant to the CEO of Relation Gate, a startup company growing at breakneck speed. Apt to listen to his gut feelings, her boss bombards her day in and day out with tall orders he concocts on a whim. Life is far from chill for Hinako, who hasn't had a boyfriend in six years. She barely even has time to sit and think carefully about her future. Each long workday ends with the same toxic thought, "I find no meaning doing this!" as she clutches a beer and lets out a huge sigh.
