The shows have a similar vibe, exploring the experiences and worries of the characters and focusing on some similar things. They also both feel very honest and deal with sensitive and tough issues.

The three girls in It's Okay To Be Sensitive repeatedly reminded me of the Belle Epoque girls, and the way that It's Okay To Be Sensitive portrayed relying on friends as an important part of dealing with difficult issues was very similar to Age of Youth.

Both dramas are about youth, friendship, and growing up. They both do a beautiful job of focusing on the things that we come to realize as we get older and the pressures and difficulties that we have to face, as well as truly capturing the feeling of being young.
