The two met because of a family reorganization. At first they didn't like each other and were both very cold, but later they learned about each other and learned some things about each other. After that, the two people treated each other a lot more gently, but they were also very awkward. At first, they thought they would grow old little by little, but an unexpected arrival forced the two to separate.
