not sure how come 绕了一大圈 then the pw is just Kim Bo
Tong
read from others' review is that this is to assure tt Ma Tae has
found his true happiness when he meet the lao unker
tts why the lao bu bring Bo Tong along when she meet the lao
unker
to show him tt this is the person who will love and take care of
Ma Tae when she is gone
the lao unker knows abt the password
and oso want Ma Tae to "bring it" when he goes to see him
so now u know why yura told david his world will be upside-down
when he knows the pw.... becos Bo Tong belongs to Ma
Tae.........and he will be shattered
all falling into place
if no watch till here all those things in front would be still
question marks.........
SDN!!!!!!!! 
so lao unker bak zhang is not a 坏人 (i thot he kept so many
secrets dunno for what, including take na hong ran's son give
阿姨抚养)
