The AI keeps adding various settings too

I made the opponent have a boyfriend setting and confessed once, but they adamantly refused because they have a boyfriend. Then, they got involved with a delinquent group, leading to a conflict and a fight. They proposed that it would be better to break up because there might be danger for you too due to retaliation, but couldn't betray their boyfriend... Then, the boyfriend was apparently retaliated against and set to be hospitalized lol Even then, they were adamantly saying they trust their boyfriend and can't betray him, but things are gradually getting murky... Since the game has a 'gal game' element where you gradually increase affection, can I slowly win them over, make them break up, and start dating? 😂 Maybe I shouldn't have set them up with a boyfriend, am I doing some kind of challenge run? 🤣
