He Drank a Love Potion!? -Work Hard, Then Play Harder-

Hinako, a researcher in a laboratory, doesn't have much luck with men. However, she succeeds in creating something that ends up making her life a whole lot more complicated: a love potion. Although she doesn't plan to use the potion, it accidently finds its way into a cup of tea meant for one of three men she works with, and she doesn't know which one drank it. To investigate, Hinako talks to Ryo - one of the men in the meeting and someone she believes has absolutely no romantic interest in her. But, to her surprise, Ryo turns to Hinako and tells her that he loves her. At a loss for what to do, Hinako decides to take responsibility for making Ryo fall in love with her and gives him what he desires. What was supposed to be a one-off, though, happens again and again, leaving her wanting more. Then, to complicate things further, the other two men claim to love her, too. What's going to happen to Hinako now that everybody wants her for themselves!?
