Artistic error because Taki has both earrings on the bottom image (she normally rocks the gay single earring)

Edit: The artist noticed (https://twitter.com/nunnun_0410/status/1844009481954590742)

上のりっきーはないのに、下のりっきーに突然イヤリングが出現している件については突っ込まないでください。今気付いた

Please don't point out that the bottom Ricky suddenly has earrings, while the top Ricky doesn't. I just noticed.
