A 'chaelisa jealous fanfic' likely focuses on the relationship between Chaeyoung and Lisa in a context where jealousy plays a role. It could be about one of them being jealous of the other's popularity, or perhaps in a more romantic or friendship - centered scenario where jealousy arises due to attention from a third party. For example, if in the fanfic Lisa gets a lot of attention from a new trainee, Chaeyoung might start to feel jealous because she's used to having Lisa's full attention in their friendship.
The jealous aspect can make the relationship more intense. For instance, Naruto's jealousy can make him realize his true feelings for Hinata more quickly. He might have been oblivious before, but the green - eyed monster wakes him up. It can also lead to some cute moments, like when he tries to be extra nice to Hinata to win her back from the 'imagined rival'.
Another theme could be possessiveness. In the fanfic, Beca might feel jealous when she sees someone getting too close to her love interest, which shows her possessive side over that person. This can lead to some interesting conflict and drama in the story.
One aspect could be the complex relationship between Sebastian and Ciel in the fanfic. Sebastian's jealousy might stem from his possessive nature over Ciel. He is Ciel's butler but also has a deeper, perhaps unspoken bond. This jealousy could add a new layer of tension to their interactions, for example, when other characters get too close to Ciel. It might lead to some interesting plot developments like Sebastian becoming more protective or overbearing in a way that both confounds and endears him to Ciel.
One possible plot could be that a new manager gives more attention to Lisa, like always choosing her for special projects. This makes Chaeyoung jealous as she feels left out. So, she starts to act cold towards Lisa.
Growth is also a key theme. Usually, through the course of the fic, Percy has to face his jealousy and learn to deal with it. This often involves him becoming more confident in himself and in his relationships, which is a great character development arc that readers enjoy seeing.
