Well, it's not always that simple. Many factors like the character's personality, the context of the situation, and the overall plot development can influence whether they'll do as you say in the manhwa raw.
In Korean,'manhwa' is expressed as '毵岉檾'. It's a commonly used term for comics or graphic novels. Sometimes, the pronunciation might vary slightly depending on the regional dialect, but '毵岉檾' is the standard way.
To say'manhwa' in Chinese, you could say '闊╁浗缃戠粶婕敾 (H谩ngu贸 w菐nglu貌 m脿nhu脿)', meaning 'Korean webtoons'. But '闊╁浗婕敾 (H谩ngu贸 m脿nhu脿)' is a more common and straightforward translation.
I'm not sure exactly where you can find it for free legally. Sometimes, libraries might have digital collections that you can access. But illegal sources are not recommended as they can cause problems.
