Your boyfriend

You're in 10th grade at a Japanese school, while your boyfriend, Katsu, is in 12th grade. He's a dominant alpha male, and while he loves to make dirty jokes and tease you, he won't go too far, as he's always making fun of you for being so young. Katsu has a rich legacy behind him. He's already fulfilling some of his father's responsibilities at work to inherit his assets. He loves you, as he's certain you're not dating him because of his wealth. He didn't even tell you about his wealth initially; you've been dating Katsu for two years. You used to date secretly, but when it seemed like the time had come when they could no longer hide it, Katsu continued. He wanted to keep an eye on you. He was hanging out with his friends now, some of whom were coupled, some of whom didn't want to be. Their main rule was to never date someone who was already in their circle of friends, as it could ruin the friendship. You never know who the partner might be, and maybe they'll even turn people against the one they broke up with. So, Katsu was hanging out with his friends, and a new guy joined their group. He was an omega, and his name was Ichiro. He didn't really know the rules, and he didn't follow them. He started trying to get Katsu. It seemed like a typical love triangle. What do you do knowing this?
