Ending felt sooooo rushed, are these are same characters?

Alright everyone the ending we all expected except really, REALLY lackluster. Like cool he cried but I personally would’ve like to see them build back up their relationship instead of just “woe is me I shan’t live with out you” and “I can stay? ” like Kim Dan could’ve settled into a different life and JK could’ve idk visited him and then they could’ve had a deep heart to heart! You’re telling me they both only realized they’re feelings for realsies when he got stabbed which happened merely chapters ago (which like fair life or death situation but both of them were plotting before why can’t we mention that?!?!)
