Kagome could also be in a state of shock. She's been taken from her normal life and thrust into this very strange and dangerous situation. But once the shock wears off, she'd likely start planning her escape and thinking about how to deal with Sesshomaru.
Kagome would most likely be very angry. After all, being kidnapped against her will is a huge violation. She would probably yell at Sesshomaru and demand to be released immediately.
Kagome would most likely be very angry at first. She's used to being in control of her own life and suddenly being kidnapped by Sesshomaru would be a huge violation. She might try to use her spiritual powers to fight back or at least escape.
At first, Kagome is likely to be angry. She's a strong - willed character, so being kidnapped goes against her nature. She would probably struggle and try to escape immediately, yelling at Koga about how wrong his actions are.
One idea could be that their relationship starts as an unexpected alliance against a common enemy. As they spend more time together, they gradually develop feelings. When Kagome discovers she's pregnant, it could bring a new level of complexity to their relationship. Sesshomaru, being a proud demon, might initially struggle with the idea of impending fatherhood but then grow into a protective and loving partner.
Another scenario could be that Sesshomaru gradually realizes that kidnapping Kagome to mate was a wrong move. As he spends time with her, he sees her kindness and intelligence, and he starts to develop a different kind of respect for her, rather than just seeing her as a potential mate. So he might let her go in the end.
A possible plotline could be that Sesshomaru has to prove himself worthy to Kagome's family and friends. Since he has a reputation as a somewhat cold and aloof demon, this won't be easy. When Kagome gets pregnant, it adds more pressure. He has to show that he can be a reliable partner and father. Meanwhile, Kagome is trying to figure out how to combine her modern - world knowledge with the ways of the feudal era when it comes to raising a child.
Love against all odds is also a frequent theme. Given their initial enmity or indifference towards each other, seeing them fall in love and become mates is a central aspect. Their relationship often has to overcome obstacles like other suitors, family expectations (in sesshomaru's case, perhaps his clan's view), and their own personal biases.
One common theme is the overcoming of differences. Sesshomaru is a demon and Kagome is a human, so there's often a story about how they bridge that gap. Another theme can be the protection aspect, with Sesshomaru protecting Kagome from various threats.
After the rescue, Kagome may start to look for Sesshomaru's help more often when she is in trouble. Sesshomaru might initially be reluctant but gradually get used to it. This could lead to a closer bond where they start to understand each other better. For example, Kagome might learn more about Sesshomaru's past and motives, and Sesshomaru might come to appreciate Kagome's kindness and determination.
