Hana becomes more and more stubborn!

Right after she got healed from her being sick last week, Hana seemed to turn into another person. More talkative (this one’s positive) yet more stubborn (quite negative).

People say that if a child gets sick, he or she might be showing progress or becoming smarter after getting healed.

Does Hana’s new character have anything to do with her previous sickness?

Please share should any of you experience the same…
