Another aspect to consider is that his crying could be a part of a ploy. In the world of 'Black Butler', Sebastian is very cunning. He might be faking his tears to manipulate those around him, perhaps to gain the sympathy of an enemy or to deceive a character into thinking he has a weakness when he actually doesn't.
Maybe it has to do with his past. As a demon, he has a long history. There could be some memories from his past life or experiences with other demons that resurface and cause him to cry. It could be related to a long - lost friendship or a betrayal he once faced.
In a fanfic, Anakin might be crying because he realizes the consequences of his actions. For example, he could be lamenting the loss of his loved ones due to his turn to the dark side. His tears could be a sign of regret for the path he has chosen, as he sees the destruction it has brought not only to himself but also to those he once cared about.
They should also consider the context. If Sebastian is crying during a battle, it could be a sign of his deep connection to the situation or the people involved. Writers can use internal monologues to show what he's thinking while crying. For example, 'Sebastian thought to himself as the tears streamed down his face, that this was a moment he never expected to feel so deeply about.' This gives readers an insight into his emotions.
There could be a lot of hilarity. Maybe they are in the middle of a demon - related task and suddenly, a magical spell makes them ticklish. Sebastian, with his pride, would try to hide it at first but Claude would quickly notice and start to tease him. This would lead to a sort of power struggle between them as they both try to maintain their composure while also trying to get the upper hand in this unexpected tickle situation.
One possible reason could be that she's had an argument with a friend at Hogwarts. Maybe she felt betrayed or misunderstood by someone she trusted. For example, if there were rumors spread about her, it could really hurt her feelings.
One possible reason could be the pressure from his family. The Malfoys have high expectations and are often involved in dark magic affairs. Draco might be feeling trapped in that family dynamic and the fear of not living up to their standards. Another reason could be his isolation at Hogwarts. Despite having his Slytherin friends, he may feel alone in dealing with his internal struggles, especially as he gets more and more involved in Voldemort's schemes against his will. Harry finding him crying could be a turning point in their relationship, from rivals to a more understanding friendship.
One popular theme is Sebastian's relationship with Ciel in different AU (alternate universe) settings. For example, in a modern AU, how they adapt to a world without the traditional master - butler dynamic. Another theme is exploring Sebastian's past as a demon, like his experiences before making the contract with Ciel. And some fanfics focus on Sebastian's interactions with other characters from the 'Black Butler' universe in unexpected ways, such as teaming up with Grell for a particular task.
A good one often has well - written characterizations. Sebastian's personality should be in - line with the original anime or manga. The ticklish aspect should be incorporated in a way that feels natural to his character, perhaps as part of a light - hearted moment or a unique plot device.
One possible reason could be a heart - breaking separation. Maybe they had to part ways due to unforeseen circumstances like one of them having to move far away for work or family reasons. Another reason might be the loss of a beloved pet. If they shared a furry friend, its passing could be a source of great sorrow. Or it could be a misunderstanding between them that led to an argument and then regretful crying when they realized their mistakes.
One possible reason could be unrequited love. In the fanfic, Chansung might be in love with someone who doesn't feel the same way. This could lead to a deep sense of sadness and cause him to cry. For example, he might have confessed his feelings but been rejected, leaving him heartbroken.
In 'Black Butler Sebastian x Claude fanfic', one of the main themes is the exploration of their complex personalities. They are both mysterious and have their own motives. This is often explored in detail. Another theme is the idea of loyalty. Their loyalty to their masters can create interesting conflicts and situations. And a third common theme is the concept of the supernatural world they inhabit. The rules and hierarchies of the demon world are often part of the stories.
