This is a spin off featuring the older brother from Challengers.
College student, Tetsuhiro Morinaga had secretly been in love with his homophobic, violent, tyrannical senpai, Souichi Tatsumi, for 4 years. In Challengers he told him his feelings and was even allowed to kiss him, and while that was enough for a while, he still wants more.
When the story starts, Souichi is going on a rampage after he hears that California has legalized gay marriage and so he is worried that his little brother, who just moved to California with his boyfriend, will run off and get married. Morinaga promises to drink with him until he is satisfied to calm him down but what happens when Souichi accidentally drinks a mysterious aphrodisiac that Morinaga's friend gave him?
