惚れ薬つくりたい同好会

After getting dumped, Harunaki met Fuyuki for the first time when he stumbled into the senior's school-club room and accidentally broke the equipment in the middle of an experiment. A mysterious liquid covered Harunaki, and before he knew it he found himself kissing Fuyuki? (It's hard to tell because of his glasses, but Fuyuki is extremely good-looking!)
