Kurt can´t stop thinking about Liam and thinks he may be gay. To make sure if he has feelings for liam, kurt uses a drug that can change the gender of people for a period of time. Then went to see Liam, but just then some random guys tried to flirt on him but Liam save him. After this he actually falls in love with Liam but what he doesn´t know is that the drug not only turns people in the opposite sex but makes them think like they are really that oppoite sex. So he falls in love with Liam because of the drug but he thought that it was because he was gay from the start. After that kurt keeps taking those drugs every now and then to go see Liam as a girl. Liam never realised that she is kurt and he actually thinks she is his type of girl lmao.
