Yamagutchi had to do the bar exam twice because she failed her first one. Her failing her first bar exam is the reason why she openly envies Saena Mogami so much because she only had to do it once and on top of that, she was the on top of her class when she graduated.
Yamagutchi assigns Saena something but scolds her later on for not listening to her.
