A song I suddenly got hooked on this morning and have been listening to on repeat, recommending it~

Just like the title lol. As soon as I woke up this morning, for some reason it got stuck in my head? My ears? It really latched on, and I've been listening to it on repeat, I just can't stop lolololol It's an old Kaito song I've known for over 1n years~ Air… - Kaito https://www.nicovideo.jp/watch/sm3277052 Honestly, I wanted to share the official/original link if possible... but when I looked it up, it's a song written/composed by 尻切れ／アリアP, and Kaito users arranged it to sing along with the lyrics... Anyway, the original music remains, but many people's arranged versions (called 'assignment songs' lol) are floating around, so it's difficult to recommend the specific arranged version I heard lolololㅠㅠㅠ I wish I could just share the audio file I have, but it's a platform that doesn't allow file attachments, which is a shame... Actually, I'd love to share the file and let many people hear it, hoping to find the person who arranged this song lololol (It's extremely difficult to find... orz
