Kimekoi! Takane no Hana 2

Megumi realized her love for Hajime thanks to a drug called HoreKime. The drug strengthens Megumi’s feelings for him and is also an aphrodisiac.

Misa, the one who invented HoreKime, has feelings for Hajime too, but she is reluctant to share them. Megumi notices this and gets Misa to drink some HoreKime so she can be honest about her feelings. The changes come over Misa instantly. Hajime is bewildered, but Megumi encourages him to answer Misa’s feelings.
