Honestly seeing jaekyung hug and kiss kim dan like that suddenly felt so weird (⊙…⊙ ...

Honestly, same. And of course that's because of the sudden timeskip to now from what happened in the last chapter. We'd expect things would have been a bit awkward after knowing how they felt towards each other and it would have been nice how they eased into things especially on how they got to be so lovey-dovey but who knows, maybe it just came naturally to them considering how kim dan was always so forgiving and compassionate and with the fact that jae kyung is deficit to love and affection that can lead to craving what he never had even if he won't admit it.
