i dont really know how to express this well but personally it feels incomplete because euiyoung always felt like a big part of their relationship (eg at the start euihyun worked to pay off the debt with euiyoung as the main motivator) so it felt weird that he hasnt shown up since after the small time skip. although its good that euihyun and taeju came to terms w their own relationship by themselves but i wanted to see them starting over as a trio :’)
of course there are other reasons why people find the ending rushed but for me this is mainly it
but regardless as someone whos followed their story since season 1 and before taejus redemption im glad they got their good ending and that euihyun has found peace
