Answer: Round and well-developed.
"Conflict" is a struggle between different, opposing forces. In literature, this opposition gives the story meaning and motivation.
There are two main types of conflict: internal and external. Internal conflict happens within the character's mind. It can be described as a struggle between different desires or emotions within a person. This is often seen in well-developed characters, as we know more about their desires and motivations. On the other hand, external conflict happens between a character and an external force.
