A Zing, also known as "love at first sight", is a special feeling that only happens when one person meets his or her soulmate, they will spend entirety with forever, you only Zing once in your life. (I know this is super lame but Aone is literally taking over my whole heart so I couldn't not make something for our favourite teddy bear 🥺) I do not own haikyuu or any of the characters of course :)
