Wow! You have quite the arsenal when it comes to evidences. I agree that it's true! I know it from experience <3🦪

(On a serious note, their friendship is so cute. The way Wonbin smiles ear to ear when Sion is speaking or performing during the awards shows is so 🫶. I also love how they share the same favorite idol- Kai, and the same favorite gyall- mee🦪)
