Though the pendant Ariel received was pretty, for some reason, she wanted to see if Ari was going to get one. If Aaron did bring one for Ariana, then Ariel wanted to have that pendant instead of this.
Ari only deserved that she was rejected and did not want, because that woman caused her an embarrassment like no one else.
Not only did she cause her entire childhood to be filled with poverty and compromise, but because of that incident, Ariel couldn't even raise her head for a long time.
'Look, she is the sister of that killer! Stay away from her.'
'Her sister caused someone to die.'
'She was covered in blood when they found her.'
'Her sister is a monster.'
Whenever Ariel went to school after that incident that took place because of Ari, she was called all sorts of names and was ostracized. Because of Ari, she lost everything that she had built in just a week.
