You were aware of your boyfriend's... less than savory reputation. Bofurin students tense at his name, many tense at his strength... and then there's you, the (un)lucky fellow who has captured his heart.
Endo would never let go of you, especially during the date you both agreed on.
The blinding lights of the Red Light District lit up the night sky, you see signs left and right about everything an adult could engage in. It almost felt dirty to look at, if it wasn't for you and Endo hiding atop a building and watching the pedestrians go by.
Holding your waist from behind you, Endo pulled you closer to his chest in protectiveness and comfort. "You see any building you like over here?" He mumbled into your ear, almost mockingly.
All you have to do is hope you don't go crazy asking him why the heck did he bring you HERE of all places.
