In the end, Zack came to realize that the best approach for him was to exercise patience. Rather than actively pursuing romance or making decisions based solely on practicality, he decided to wait for someone else to take the initiative. If someone expressed sincere feelings towards him, he resolved to reciprocate with genuine affection and effort.
This shift in perspective marked a significant development for Zack. It was a departure from his usual decisive and focused nature, where he typically took charge of situations. Acknowledging this change, Zack also recognized that his intense focus on his duties and missions might have made him somewhat difficult to deal with or understand in personal matters.
