I feel the author should show them actually having a connection with each other so it’s easier to read
Nobody really brings up their childhood as a good reason for them to work things out or nostalgia for the good days between them, there's not really a connection between them in the present as we said too. Despite having the cliche childhood trope, the reason so many people dislike this trope in manhwas and kdramas is because most of the time it fails to form a connection which is its main purpose. If the current situation overwrites the past easily as it is...I would say it needed more depth. But maybe there's another type of connection they might have later on?
YESSS! WORTH THE WAIT ALL THE WAYYY!
