Does chapter 69 from fluttering feelings exist?

You should look at the Fluttering Feelings [SPOILER THREAD] for information like this. The artist has been seriously ill and unable to work on this, so of course there's no chapter 69. Let's worry about Ssamba and hope for her recovery before we worry about the story.

This post in that thread gives the most recent information on Ssamba as of a few days ago.
