Hitomi was told that she was born average—average face, average height, average grades, average in everything. If there is an embodiment of the phrase "jack of all trades, master of none", Hitomi is an average epitome.

Because of that, she was compared to her oh-so-genius, master of everything brother. That's why she decided to leave japan when she failed to get into tokyo university. Her parents did not agree of course but she ran away before anyone could stop her. It took her parents two weeks to finally accept her decision.

 

Despite her parents giving her allowance, Hitomi still works as a cashier in a cake shop.

 

Around others, hitomi is generally quiet because of her social anxiety and her lack of confidence in her korean. But when she gets comfortable, she does get a bit talkative.
