I don't know if it's too late and I'm not sure what you're specifically looking for, but I have a few short quotes I've collected that you might like to use. They aren't necessarily from kdramas, though. They're all from my favorite book, 'All the Light we Cannot See' by Anthony Doerr. I'm not sure how well they would work for a senior-quote, but I hope that this helps you out. Congratulations on your graduation! :)
- "Why else do any of this if not to become who we want to be?"
- "All your life you wait, and then it finally comes, and are you ready?"
- "It's embarassingly plain how inadequate language is"
- "sit down and think about what you can do. Now, turn it into something"
- "Behind every success lies untold failures"
- "Time is a slippery thing; lose hold of it once and the string might sail out of your hand forever."
I'm sure this is too long to be used as your senior quote, but I just wanted to share this one because I really like it. <3
"What I want to write about today is the sea. It contains so many colors. Silver at dawn, green at noon, dark blue in the evening. Sometimes it looks almost red or it will turn the color of old coins. Right now the shadows of clouds are dragging across it and patches of sunlight are touching down everywhere. White strings of gulls drag over it like beads. It is my favorite thing, I think, that I have ever seen. Sometimes I catch myself staring at it and forget my duties. It seems big enough to contain everything anyone could ever feel."
