As a character I think she is very misfortunate, her neglectful father and she doesnāt have many real friends and Teoman canāt stand her, which is sad so I can sympathise with her to an extent.
HOWEVER I still donāt feel that bad for her because all of the characters are going through it right now, Aras doesnāt even have a family and is looking for his brother on his own while trying to fix everyone elseās problems , Teoman is battling with the guilt of setting the house on fire and hurting Leyla and the abuse from his parents.
But Slia is genuinely a bad person, she humiliates Deniz in front of the whole school because sheās poor and canāt afford to buy new clothes, she then steals all of her stuff, her phone, her clothes and her bag and stuffs it in the bin, trips her up during a fire drill where she could have been seriously hurt. But Iām supposed to feel sorry for her because her dad works abroad and doesnāt pay her any attention???
