Though Enu's mood is by default happy and superior, zhes mood changes in a heart beat. If something starts to not go zhes way zhe will throw tantrums, if something makes zhe slightly sad zhe will bawl, if something is slightly pelasant zhe will be beaming, and so on.
This is not due to zhe being incredibly spoiled or the likes, but rather that zhe doesn't have the biggest attention span and goes all in in everything zhe does, so if the mood changes, zhes will too, and zhe won't really be able to tell what just happened unless zhe gets some time to think about it.
Enu will often be thinking of one, if not both, of two things by default as well; food, and sex. These are, not so surprisingly, also the two things zhe seeks the most in zhes free time, and will often innitiate social interactions with flirting, or straight up trying to eat the other person.
Zhe has, due to this and other reasons, gotten the rumor of being not much different from an animal.
