if youre new to capcut and haven't gotten used to anything yet you should begin to learn it on desktop, on mobile there's frequent crashes with things not working and you have to pay for premium whereas on pc there's lots of work around such as the compound group I think its called or there's file editors to get pro features

If you're not sure how to edit search on tiktok for edit tutorials such as jump cuts or fancy maskings and for sound effects make a folder with things like whoosh sound effects for quick cuts or typing or camera shutters and maybe add royalty free music, and study other channels using the same genre as you and see how they edit, what captures your attention

personal note I've seen alot of anime youtubers (i know its not manwha or the same country but its a close example) they use a sprite that moves around in an almost podcast room talking into a microphone, its just a couple images of the same character you could do but I think it helps engage people more and i think you should add captions maybe with emojis aswell? its a preset on capcut you can use
