I love their relationship! They are best friends, they treat each other with respect and concern. No matter their relationship involves romance, or not, they are a really good couple that will last long. Kao sees Up as a perfect "idol" to develop himself and Up sees Kao as a soulmate, a safe zone ✌👏
lol how cute...but why does Kao look even more handsome here? so nonchalant and fresh mm my clown brain says it's couse in his head there's only Up in this moment 🤣 jk we'll never know but damn this vibe fits him
