Inraku no Biyaku ~Omoi o Yoseru Ano Ko mo Namaiki na Ano Ko mo Yaritai Houdai~

An ordinary guy was in love with his classmate.
He was too afraid to tell her, and then some bratty girl
talked trash, and all his hopes were dashed.

That is, until the day he obtained an aphrodisiac
that completely changed his life.
