Since I'm not familiar with this particular light novel, I can't give a definite answer. However, in many light novels, a kiss between two characters often serves as a significant moment in their relationship development. It could be a turning point, a sign of deepening feelings, or a moment of great emotion. If the relationship between Jinshi and Maomao in the novel is of a romantic nature and the story follows typical romance plotlines, then there could potentially be a kiss scene. But again, this is all speculation without having actually read the novel.
Well, in a fanfiction plot, Nicole could be hurt while trying to protect her partner. For example, if there's a bomb threat in a building where they are. Nicole would shield her partner from the blast, resulting in her getting seriously hurt with burns and fractures. Or perhaps she gets into a car accident while rushing to a crime scene because of a mechanical failure in her vehicle.
One possible plotline could be that Tohru gets physically hurt during an accident while helping out at the Sohma house. Maybe she's climbing a ladder to fix something on the roof and slips, resulting in a sprained ankle or a cut. Another could be that she gets emotionally hurt when she overhears some of the Sohma family members saying unkind things about her, not realizing she can hear them. It could make her question her place in their lives.
Yuki would likely be very concerned. He has a soft spot for Tohru and would probably rush to her side, trying to find a way to help. He might even blame himself if he thinks he could have prevented it. Kyo, on the other hand, would initially be angry, but that's just his way of showing worry. He would be more hands - on in getting her the help she needs.
Physical hurt might come from a powerful magic spell. Let's say an evil sorcerer casts a spell that drains Yami's energy and causes him pain. His struggle to overcome this and regain his strength could be a central part of the fanfiction.
After Nicole gets hurt, her partner could be filled with guilt and determination. The partner might focus all their energy on finding out who was responsible for Nicole's injury. For example, if it was a criminal act, they would dig deeper into the case, leading to new revelations and a more intense plot. Meanwhile, Nicole would be in the hospital recovering, and there could be emotional scenes between her and her partner as they deal with the situation.
Simon might be in a bit of a panic. Since he's her friend and also not as used to the dangerous situations as the other Shadowhunters. He'd try to do whatever he can to help, like getting help from more experienced Shadowhunters or trying to comfort Clary while she's in pain.
In some fanfictions, it could be a new character, perhaps a young and brilliant inventor who idolizes Iron Man. This person discovers Iron Man's injured state and uses their own unique skills and knowledge, which they've developed while studying Iron Man's technology, to nurse him back to health.
One common scenario could be during a battle with the villains. For example, when facing the Serpentine, Jay might get caught by their venomous attacks which could hurt him badly. Another situation could be an accident while training with his fellow ninjas. Maybe he misjudges a move and ends up crashing into something hard, like a rock or a wall in the training area.
Macgyver would probably be very worried. He'd quickly assess the situation and try to stop the bleeding if she was bleeding. He'd use his resourcefulness to make a makeshift stretcher or bandage.
