The two talked in length that day...
It seems that Xiao Bai was younger than his elder brother by a decade or so, and he was without a family after his brother was murdered.
His brother's girlfriend who was like an elder sister to him was also dragged to that hell a few days later;
he still vividly remembers the memories of that day... she had talked to him all about what happened and had cried, she had asked him to stay happy, but if he gets the chance to, he must get his revenge... He still remembers the sad look in her eyes from back then, she must not have wanted for him to exact revenge, but she had been that desperate back then...
Later he came to C-country and joined the army and just like that for the last 16 years or so, he has been putting his life on the line, getting merits and hoping for that single chance to get that man to his knees and plea for mercy.
