So the story starts off with the uke being saved bye the seme on the train when he was gonna faint or something like that. They are both university students and when the seme runs into the uke at school he confessedhis love for him like the next day. The uke is in a psychology major and bring up the topic of "the bystander effect" or something like that where if someone is in trouble no one would help but since the seme helped him he feel special.
