I stumbled upon a shocking news in London.

Recently, I encountered a big dilemma in a London rental. There was a guy in a group chat who claimed to be adopted by his parents from an orphanage. He just turned 19 and was preparing to attend UCL in London. He is not his parents' biological child, and he is aware of that. He also has a sister who is 21 years old and studying at UAL. His sister has never had a boyfriend until now. Suddenly, their mother told him that if his sister graduates without finding a partner, he should marry his sister. After all, they are not blood-related and cannot be considered close relatives. The guy mentioned that he was in the process of preparing to study abroad. Besides applying for university offers, he also needed to find accommodation. Initially, he planned to consult his sister for any advice or recommendations. However, when he heard his mother's suggestion, he was shocked and immediately refused. After all, he has always considered his sister as his own sibling since being adopted. How could he possibly marry his own sister? He found it difficult to overcome this emotional hurdle. Then his mother started giving reasons, saying that firstly, there would be no need for a dowry or bride price if he married his sister because they are already a family. Secondly, since he was an orphan with no other relatives, marrying his sister would not only avoid conflicts between in-laws but also strengthen the bond within the family. Thirdly, he was about to start university, and this semester he could go to London together with his sister. The family would continue to support his tuition fees, and they could find a large apartment near Zone 2 for them. The rooms would be 26 square meters each, with private bathrooms and inclusive bills. It would only take a 1-minute walk to the bus stop and a 3-minute walk to the subway station. The area had excellent bus connections, and there were nearby supermarkets, pizza shops, cafes, convenience stores, and more within walking distance. The best part was that the apartment had high-speed internet. The commuting time to their respective schools would be similar, and the public transportation time would not exceed half an hour. From Monday to Friday, they could go to school independently without disturbing each other. On weekends, they could go for coffee, have meals together, and build their relationship. After he graduated, they could directly get married, and their family would buy them a house in London. They could both work and live there, which would not only relieve the family's worries but also solve both of their marriage matters at once. While it sounded somewhat reasonable, it was also highly unreasonable. He told his sister about this situation, and she was equally speechless. Initially, his sister planned to find a place for herself first before helping her brother find accommodation, which would also avoid the issue of living together. However, due to the exorbitant property prices in London that kept increasing, the 26-square-meter apartment arranged by their family seemed to offer good value for money and had spacious rooms. His sister really wanted to live in that apartment. She planned to rent two rooms, one for herself and one for her brother. But she didn't know how to bring it up with her brother, feeling a bit awkward...
