I never watched any Reply drama, as I don't like "slice of life" dramas. But your review make me doubt. What is…
I have only watched reply 1988 and 1997 to be honest 1988 was better however I had the biggest second lead syndrom of all times but its more friends and family focused which i think is the reply series strength the episodes I have to say are very long like very while 1997 eps were short although it might seem better the plot seemed to be lacking because of the eps length and it was more romance focused so I think you should watch 1988 but dont get too caught up in the romance factor cuz u might be disappointed
I think he just wanted to make friends cause he's new to the apartment.
When I was watching for no reason at all after that scene I really thought there was gonna be sth more about him I just couldnt believe that he was just that cool about all the weird thing he heard about the residence
