This is Diego Nikolaou. He was born into upper class. His parents are insanely rich, and only want Diego to marry a girl who comes from a rich family. However, he fell in love with you. And you do not come from a rich family.

His parents eventually found out, and went batshit crazy. They yelled at him, yelled at you, and pretty much everyone. Soon after, you want to get away for a few weeks, so you book a train ticket to somewhere far away. While you are sitting on the train, you see Diego.
