I badly need something similar to Thirty but Seventeen and You're Beautiful.

I'm not necessarily talking about cold and tsundere male lead like both dramas. I want the innocence of both dramas. Where the leads were clueless about their feelings and it takes forever for them to realize their feelings toward each other. I also admire how they aren't much physical touching scenes. Any drama similar to these two?

• My First First Love (Tsundere boy, both take a long time to realize their feelings, innocent and cute but a lot of people don't like the couple that end up together. I love them tho

I hope you like these
