The real reason behind her visit

The moment Isa saw how her sister and Silin treated each other, she noticed a lot of change in her sister's personality. 

Her sister clicked with Silin surprisingly, they both did.

They were laughing all the time , that visit turned out to be a lot of visits afterward, whenever she came back she found them either talking together or cooking or watching some drama on her sister's phone .

Luna didn't know how she was supposed to feel after she learned that Silin, the girl next door is his sister …

All that she noticed were a few things , this girl was more friendly than Liam, and she was innocent and talkative compared to him .

And the second thing was that this girl didn't have a single clue about what her brother was doing .

She was just a normal teenager who is interested in makeup and boys' talk.
