Why does she assume other girls would play around with him?
Because Maid-Yamato lusts for her young master, she is basically projecting her desires onto them.
That reminds me, it was decided that I'm going to the Comiket with Akigumo.No, it would rather be dangerous for Young mas... for Admiral to get cajoled by Akigumo-san or other females...This can't be...! To let Young master to go to such dangerous place. If he were to get injured, there's no way Master would forgive me...!What did you just say!?
