In English, 'suddenly' is often used to transition between events in a story. In Japanese, overusing 突然 can sound unnatural. Instead, use sentence-ending particles like 〜と, 〜たら, or simply describe the sequence of events without an explicit adverb. For example, instead of 'Suddenly, a man appeared,' it may be more natural to say 男が現れた (A man appeared) or ふと見ると、男が立っていた (When I casually looked, a man was standing there).
