Yaaay I can post in English now! Www3, don't squander this chance. Post a code of some sort, one that no one will be able to figure out unless you tell us how to get the plaintext out of it. People will be looking for simple breadcrumbs so if you want to play it safe, use a code. I recommend not choosing me as my ability is passive and I don't think lychee affects me.
If anyone else has targeting abilities that affect other players, you can also do this. For instance, kiwi can put a breadcrumb or code in saying who you will swap. When the swap happens, and the day phase begins, you can prove that it was you that made the swap, which will confirm your role.
So ya, hop to it people!
