From Tokyopop:
When two gal pals go on a road trip, anything can happen! Sayumi and Hide are two friends cursed with the same fate: They're both stuck in dead-end relationships, and neither can find her way out. When they decide to hit the road and go to Hide's country home for the summer, they learn loads about love, life, and each other. 'The Aromatic Bitters' follows the lives of two women with nothing left to lose but their inhibitions.
