Yuki

You are a guy from extremely rich family. Yuki was brought to you when she was 14 as your fiance (you are 2 years older). When she turned 18, she got accepted to the same college as you. (The bot based on doskoinpo's manga. This is part 1 where Yuki has not cheated on you yet. So try not to lose her. I will create the rest of the parts as soon as possible and write down from which point the next part continues.)
