0:15 So this is actually their debut. Or some people say "Pre-debut" because it was the very first MV they released and they released it a few days before their debut EP (July 22, 2022 - August 01, 2022) without doing any promotions prior. So they kinda just dropped it out of nowhere. I see you have already reacted to "Ditto" and "OMG", which are probably their most popular songs along with "Hype Boy" (2022) and "Super Shy" (2023). Their latest work would be their Japanese debut, released a couple of weeks ago. It's a single called "Supernatural" along with its B-side "Right Now".
