i think what makes shujin trio such an appealing dynamic is that for once, the girl isn't the smartest, most responsible and most put together of the classic shoenen 2 boys and 1 girl trio. ann is just as much of a disaster as ryuji she just plays it off a lot better and so it falls on to ren to keep them on the straight and narrow but ren is not interested in being straight so he falls into their bullshit just as easily and willingly. but he is also a progenitor of bullshit himself and poor morgana is actually the one holding the leash bc guys PLEASE. ONE OF YOU HAS TO DRIVE.
