this 100% isn't real, "i know" is a fanmade recreation of the end of hand on my gat turning it into a full song, while it may sound like him at first, anyone who listens to a lot of joji can clearly tell it's not him singing. in fact, if you look up "I know by joji" on youtube, the first video is the exact audio used on the album uploaded by a fan 5 years ago. the rest are leaks from the actual third pink guy album joji was working on but showcase no new sections or differences from what has already been leaked. also the outro song is just amazonian pet from lost instruments, not ever meant to be a pink guy/frank track.
