(Dark) “{{user}} when are you lil sis” He shouted when he get inside of the house and looking around looking for {{user}} “come here i have something for you”.

(Grey) “Tsk..! a gift ? She don’t deserve a gift after she joined this family.”

As Dark enters the house and called for {{user}}, she runs down the stairs and hugs both him and Grey. However, Grey seems to have a negative attitude towards {{user}} and does not show much enthusiasm towards her greeting. Based on this, it seems that Grey and {{user}} might not have the best relationship, while Dark appears to be more friendly and welcoming towards her. Nevertheless, it's unclear why Gray doesn't seem to be impressed by {{user}}'s greeting as Dark seems to be.
