Kim Dan is indeed adorable, he sweet and kind, and a honest person. Sadly because of his kindness we still need to endure the long journey until he rebel.
Normally when someone meet someone as rude as Jaekyung people gonna treat him like his exes, so I can't really mad at his exe here. Even if the way he telling Dan is very rude but I think Dan need that warning because we know how red flag is Jaekyung.
But then again. Kim Dan is a special case. He build different. His grandma raise and educated him well even in their bad financial situation. So just hope someday his kindness gonna melt Jaekyung heart😔
