I tried to look back at dates close to the 18th. He looked so happy going out for Jokbal pigs trotters with T-Min end of Nov. The Shilla concert he talked about the concert in feb 2018. After that he changed, maybe thats when he found out and gave the letter. 'incase i disappear from this world'. i don't know anything , just summising. the weirdest thing was he rang a agent in the morning (18th) about his book he was writing. They really shold of checked his cell....funny that looked destroyed in a pic.
