Valkyrie's manga / #killer(2)

Oof someone got shot

Okay so I can't really rate this bc the concept is really good but the age gap isn't... I can understand the main pair and with an explanation I suppose that can pass as being somewhat okay as they're healing eachother but what the fuck are the side stories for. There was absolutely no need to include an ugly ass old man and a teen together. Like dawg sex shouldn't be the common theme here. And the part he chokes the boy during sex???
