Tbh, i hadn't listen to OMG dolphin before. So when onewe just make their own cover of dolphin: and of course i've listen to it. Weves are small fandom so WE haVE to be more dedicated. Back to dolphin, when i heard onewe cover, i find out that this song is cute and kinda catchy. So i decide to hear the ori one: I'm right, this song is indeed cute and catchy. Now, i know why IU love and promote this song. This song is good and this song also reminds me of IU vibe.
