Etymology
快 combines 忄 (heart/mind) with 夬, which likely contributes the sound and may suggest a sense of release or ease. The character expresses a pleasant, cheerful state of mind.
Meaning mnemonic
The heart radical 忄 beside 夬 looks like a heart opening up. Imagine your heart feeling light and open, bringing a cheerful, comfortable mood.
Reading mnemonic
For カイ, picture a cheerful person flying a colorful kite: kite -> カイ, and the happy scene matches the pleasant, agreeable feeling of 快.
