Recently, he wrote, "I feel like a large crisis is about to happen in my life. �It'll probably become clear then which people trust me, those kinds of people. �I changed a lot, too, but I am positive that a lot of people changed with me during the eight years I've promoted [as a singer]. �I'm getting sick of it. �I think I've only been looking at a dream that was too ideal. �Looking squarely at the reality, I find that I have been too stupid."

His latest Tweet included the selca above with the cap covering his eyes as he said, "With my mother on a rainy day. �A drink as I'm feeling down."

Based on these tweets, Hongki seems pretty upset about something. �Already fans are responding with encouraging messages, so hopefully, these thoughtful acts will help him to cheer up and overcome whatever difficulty he is facing!
