Maybe for someone, promises are just childish actions that our childish brain made. Maybe it's just a thing that we shouldn't take seriously in order for us to not get hurt.
But for Yohan, he really took it by heart.
Yohan and Leonard made a promise back when they were just kids. It was a promise made by their innocence and curiosity. Little did Leo know, his bestfriend fell inlove with him the same day they made the childish promise.
Ten years later, Leo looks like he forgot about that promise and the only person who kept holding onto it was Yohan. Will Yohan be able to keep holding on? Or will he just give up their childish action that they had sealed with a kiss
