A possible plot is that the male rival discovers Ayano's yandere side early on. Instead of being scared, he decides to try and help her overcome her dark tendencies. This could lead to a series of heart - to - heart conversations and attempts at reform. Or, perhaps there's a misunderstanding where the male rival thinks Ayano is in danger and tries to protect her, which makes Ayano question her own motives towards him. Also, they could be paired up for a school project and through the long hours of working together, a unique relationship forms between them.
To create a believable relationship, you need to focus on their interactions. Start with small things like shared glances in the hallway or accidentally bumping into each other. Then gradually build up to conversations. For example, the male rival could compliment Ayano on her hairpin or something she's wearing. Ayano, in turn, could show a bit of shyness or nervousness that is endearing.
One common theme is obsession. Ayano is typically obsessed with Taro, which drives most of the plot. Her yandere nature means she'll go to extreme lengths to have him.
Power dynamics is a common theme. The yakuza represents a certain kind of power in the criminal underworld, while Ayano has her own power of manipulation in the school setting. Their interaction often involves a struggle or negotiation of power.
