Tsubaki Omori is a recent graduate with a major problem. Her mom left the country to fangirl over her favorite Korean pop idol and took all their money with her! Good thing Tsubaki found this flyer for a job ”assisting with a traditional Japanese art form.” It turns out to be calligraphy brush making， but with a secret ingredient! Now Tsubaki is stuck between a rock and a hard place. Can she throw away her reservations so that she can make enough money to survive!?
