Reply 1988 is one of my favorite dramas and when I started watching Sunny, I started getting the same vibes and feels I did while watching that drama.
Reply 1988 is a drama while Sunny is a movie, but both occur in a similar time period in the past and evoke nostalgic feelings even if you didn't live through that time period yourself.
The friendship theme is strong and both the drama and movie are slow paced, yet interesting, funny, and realistic.
You'll find yourself laughing, crying, feeling sentimental while connecting to all of the characters!!! :")
