The English adverb "readily" has two main uses: (1) doing something willingly and without hesitation, and (2) doing something easily or without difficulty. Japanese expresses these meanings with different adverbs, phrases, and verb forms.
Expressing that someone does something gladly, without reluctance, or promptly when asked.
An adverb meaning 'willingly', 'gladly', or 'with pleasure'. It implies a positive, cheerful attitude. Commonly used when someone agrees to a request or offers help.

快く is the most common and neutral way to say 'willingly'. 喜んで is more emotional and often used in polite offers. 進んで emphasizes volunteering or taking initiative, not just agreeing.
