idk how senior quotes worthy these are or the vibe you're going for, but some Chuuya quotes i appreciate (in addition to the ones i already posted) that could work:
- "obviously, i'm never gonna give in. i can keep this up forever."
- "i'm gonna do what i need to do. that's who i am."
- "that's for me to decide. not you."
- "i'm still growing!"
- "who's heartbeat is it, then? mine?"

some other quotes (non-Chuuya)
- "would you like to hear an android joke?" (big fan of this one tbh)
- "a bird born in a cage doesn't notice that it's a prisoner." / "do you like birds?"
- "do you really think there's any value to this thing we call living?" (LOL 🥀)
- "as if bruh"
- "do not pity yourself."
- "not once have i regretted the things that i did. i only ever regret the things that i did not do." / "i want no regrets."

ANYWAYSSS i hope this was a little helpful or maybe not idk i wasn't sure if some would come off corny or obvious without context 😭
