Endlessly longing for but never interacting with her crush, Tsukimi's love ends in heartbreak when she sees him with another girl. Hoping to recover from this, she approaches the nerdy Chemistry Club member Okino, who is not only quite attractive but is also rumored to have created a love potion.

Though the rumor turns out to be true, Okino warns her that the feelings created through consuming the potion are only an artificial love. As Tsukimi spends more and more time with Okino, she finds her heart suddenly wavering in his direction—could this be "true" love?
