One idea could be an OC who is a new transfer student at the school. She has a unique hobby like astronomy and catches the attention of the main characters. Maybe she helps Naoki with a school project related to the stars, which leads to a new friendship and some jealousy from Kotoko.
One idea could be a modern AU where Kotoko and Irie meet in a completely different setting, like at a music festival. Kotoko could be a struggling artist selling her handmade crafts there, and Irie could be a medical student taking a break from his studies. Their initial encounter could be a bit rocky, just like in the original, but then they gradually fall for each other as they discover shared interests in things like environmental causes or indie music.
Another option is to pair the OC with Kotoko. They could be like sisters. The OC could be more level - headed than Kotoko and help her out in her relationship with Naoki. For example, the OC could give Kotoko advice on how to handle Naoki's moodiness, and in return, Kotoko could introduce the OC to all her friends at school.
Another storyline could involve the use of 'Itazura na Kiss' character personalities in the 'Harry Potter' universe. Imagine if Kotoko was a Muggle - born witch at Hogwarts. Her clumsy and determined nature would likely get her into all sorts of adventures. She might constantly be trying to prove herself to the more 'Naoki - like' students who are brilliant at magic, and along the way, she might discover new spells or magical artifacts that no one else had thought to look for because of her unique perspective.
Maybe there's a party where Kotoko is dancing with different guys. Naoki, who usually acts nonchalant, can't hide his jealousy this time. He might pull Kotoko away from the dance floor in a rather possessive manner. Then he has to deal with Kotoko's confusion and his own realization that his jealousy stems from his love for her. He could then start to be more affectionate towards Kotoko in his own way.
