well haesoo says in the next (or next next?) chapter that he feels a little awkward because it's been so long since they were together like this. also theyre very new at openly voicing their affections to each other so there's that too
personally i dont think it was that awkward though, they were bantering like old times which was nice

well i dont think so at all (just stating my opinion)
for example: joowon saying he thought he was gonna die -not literally obviously- during the 3 years haesoo was gone and then quickly changing the subject because he gets awkward and flustered. showing eo open and genuine affection is new to them. so i think the author depicted that feeling well and this chapter seems all genuine and sweet~
It probably is just me but something about this chapter just seemed off. Sure it could be awkwardness from being apart but I don’t know.
