Today I watched a movie "men in black 2".
This is a story about people who manage aliens and try to keep secrets about that for safety.
J is a man who needs a partner since his ex-partner "k" wanted to retire and delete his memory. So J had to delete his memory and find a replacement.
But in MIB2, Earth was in trouble. An alien called 셀레나 came Earth to get something important. J needed K's help. For that reason J tried to remind him and overcome it.
I'm not sure if I explained it right. :)
Please let me know when you have questions or something.
