Paradox

Quadruplet rabbits Felix, Aiman, Freya and Lily are a paradox for they are similar and different at the same time. Much like with twins, they wish to be their own person rather than be seen as just part of a matching set. They try so hard to be different from each other that they accentuate their good points and their bad.
Felix is athletic but acts dumber than he is out of social expectations (i.e "dumb jock")

Aiman is smart but only at complicated things, not easy things.

Freya loves anime/manga but only trusts fellow anime/manga lovers (including her siblings)

Lily is so sincere that she tends to come off as too brutally honest, therefore she's thought of by many as meaner than she actually is.
