Is this a yaoi??

Ha ha why does this has a yaoi tag !! ?? There is no smut at all. No , it's Shounen Ai, with circle of friends and action/fantasy.
there is sex but only implied, we don't see it.
Maybe it's not the '' cute kind '' of Shounen Ai, coz the ML is borderline sociopathic but they are quite good to each other, so it's fine to call it love.
