Ah~ Better than anyone I've met so far

Made a new friend today and immediately mined 20 times. A regular buyer came, so I started putting new flowers and other items on the market, but the new friend immediately bought everything as soon as I listed it. So I had no choice but to list the same items again, and they were immediately bought out again. This time, I made sure they weren't online before listing... but 2-3 minutes later, they were instantly bought out again. I want to tell them they're not my only friend. Do you guys have anyone like that? Does it not bother you at all? I'm tired already this morning 🥲 By the way, the new flower is Zinnia (green).
