"You…" Lin Lin slowly retreated step by step because she wanted to erase the memory of the person who had the same face as the person in front of her but was different.
The person who Lin Lin considers an older brother in the modern world is a man who sincerely loves him because, at that time, Lin Lin accidentally saved her from danger.
Then Lin Lin and that man often went on missions together and shared their troubles. However, the man's end was tragic.
The man had to be captured by the enemy and finally tortured for three days and three nights until the man could no longer endure even though Lin Lin had come and conquered the enemies who had tortured the man.
When Lin Lin came to the prison where the man was locked up, the man was not strong enough to live anymore and apologized to Lin Lin for not carrying out the mission with Lin Lin anymore and had to make Lin Lin carry out the mission alone.
