Based on the context of your question, the "other" and his grandmother's relationship went through three distinct phases before he studied abroad:

1. Childhood Dependence: This initial phase was characterized by a strong bond where the grandmother played a crucial role in his upbringing. She was a constant presence, offering care, support, and guidance during his formative years.

2. Adolescent Rebellion/Distancing: As he grew older and entered adolescence, a natural distancing occurred. He might have started seeking more independence, leading to occasional conflicts or a sense of detachment from his grandmother's traditional values or expectations.

3. Pre-Departure Reconciliation/Appreciation: In the time leading up to his departure for studying abroad, a sense of reconciliation and renewed appreciation emerged. Realizing the impending physical separation, he began to value his grandmother's wisdom, love, and the significance of their relationship. This phase involved heartfelt conversations, shared memories, and a deeper understanding of each other's perspectives.
