Changing partners in a manhwa can be a risky move. It might work if it leads to more complex storylines and character growth. However, if it's done just for the sake of it, it could disappoint readers.
Well, it could go either way. Maybe if the current partners aren't working well together or if there's a better match for the story's development, then changing partners could make sense. But if the existing partnership has potential and just needs some growth, then maybe not.
The storyline of 'All I Want Is You' manhwa is centered around two people finding true love against all odds. The appeal is in the well-developed characters, the beautiful illustrations, and the touching moments that make you root for the couple.
It could go either way. If the current partner isn't contributing much to the plot or character development, a change might be refreshing. But if they have potential for growth, keeping them could lead to more compelling storylines.
