We met at the tutor's home and started a sibling relationship between a college student and a graduate student just before graduation. There was no space or time. When the love was strong, they encountered life choices. Facing the tutor's comfort, they never thought about giving up, but they encountered unimaginable facts and everything changed. When we met again five years later, she was already the mother of a five-year-old daughter, and he had already learned a lot and wanted to settle abroad. Whether it was hate or love, everything was in nostalgia.
