A common trope is the 'fish - out - of - water' situation for Hyung Suk, and Jae Yeol being the one who either helps or hinders his adjustment. For example, if Hyung Suk suddenly finds himself in a new and unfamiliar social setting within the Lookism universe, Jae Yeol's actions towards him can drive the plot. There's also the trope of 'hidden depths', where both characters may seem one - dimensional at first but as the fanfiction progresses, their true personalities and motives are revealed, often leading to a deeper connection between them.
In Lookism fanfiction, the 'power imbalance' trope is often used with Jae Yeol and Hyung Suk. Jae Yeol may have more power, whether it's social, physical or financial, and this can create an interesting dynamic. Hyung Suk may initially be at a disadvantage, but through his own growth or with Jae Yeol's help, he tries to level the playing field. Also, the 'redemption' trope can be applied. If Jae Yeol has made mistakes in the past, his relationship with Hyung Suk can be a path for him to redeem himself and become a better person in the context of the fanfiction.
One popular trope is the 'enemies - to - friends' or 'enemies - to - lovers' trope. At first, Jae Yeol and Hyung Suk may not get along due to differences in appearance or social status. But as the story unfolds, they gradually come to understand each other and form a bond. Another trope could be the 'mentor - mentee' relationship, where Jae Yeol, with his more worldly and confident attitude, guides Hyung Suk. This can involve teaching Hyung Suk how to handle the social hierarchies in the Lookism world.
