In a love story, Jenny could play various roles. She might be the girl-next - door type who unexpectedly finds love. For example, she could be the one who starts as a friend to the male lead and then gradually realizes she has deeper feelings for him. She could also be a character who has to overcome obstacles in her love life, like family disapproval or misunderstandings with her partner.
The likability of Jenny in the love story can also be influenced by the context of the story. If she's in a situation where she has to fight for her love against great odds, and she does so with grace and determination, that can make her very likable. On the other hand, if she's constantly causing drama without any real reason or growth, it would make her less appealing.
I'm not sure as I don't know the details of 'jenny love story', but I assume Jenny is one of the main characters. Maybe there's also a love interest whose name we don't know yet.
