According to a news outlet, Nine9 was handed the note two days prior to Jonghyun's solo concert, which was held for two days from December 9 to 10.
She told him "not to think of doing anything extreme."
The two showed the letter to the late singer-songwriter's family, which spoke of his deep troubling thoughts that unsettled his mind.
Nine9 bonded with Jonghyun as a regular guest on the radio show Blue Night, of which Jonghyun was the host.
Jonghyun was found unconscious from cardiac arrest at a studio apartment in Cheongdam, a suburb of Southern Seoul on December 18. Although he was moved to a hospital nearby, he was pronounced dead shortly after.
