Another theme could be self - discovery. The oc might be on a journey of self - discovery while being involved with Jasper. And the lemon elements can be seen as a part of that journey, a new experience that helps the oc understand themselves better in the context of the relationship. Also, power dynamics can be a theme, especially considering Jasper's character. The relationship might involve some give - and - take in terms of power, which is sometimes reflected in the lemon parts as well.
Conflict is also a common theme. There could be external conflicts like others not approving of the jasper oc relationship, or internal conflicts within the characters themselves. The lemon parts can be a way to either resolve or intensify these conflicts. For example, a moment of passion might be a turning point in resolving an argument between them, or it could create more internal turmoil for the characters as they struggle with their feelings.
Love and relationships are also a big theme. Whether it's a romantic relationship between the OC and Jasper or a strong friendship, the interactions between them are central. The OC often brings out a different side of Jasper that we might not see in the original books.
A lot of these fanfictions explore the idea of the OC being special in some way. Jasper's possessiveness then stems from his recognition of that specialness. It could be something like the OC having a unique power or personality trait that attracts Jasper. And there's also the theme of jealousy. If other characters get too close to the OC, Jasper's possessiveness kicks in and he might show signs of jealousy.
