@Shira Ya she did explained But she didnot know that the man she is talking to is her brother." it's not like she has any other family other than her brother,"How lonely must have he been all these years clinging to the last hope of finding his sister And respecting her wish to not meet Him? and After all her being his bloodline saved her from execution and he didnot force her to go back. Thats being mature and thoughtful of him.
