It's hard to find a perfect solution in this world; Harano can't have it both ways.
Ah Man repeatedly confirmed that Ah Qing had neither thought of marrying Harano as the main wife, nor was it possible for her to do so. In fact, that would be a burden for her. The next morning, after waking up, Harano secretly observed Ah Qing's expression several more times and discovered that she was just as usual—with no trace of sorrow or hurt—so he gave up his indecision. In this era, the world is still quite friendly to someone "above others" like him. Everyone tacitly assumes he should have multiple women—a main wife plus several concubines, and even a dozen maids for good measure, ideally producing offspring in the house every day.
Since there was no longer an emotional factor, if he weighed things from a purely utilitarian or power-development perspective, then rapidly recovering his own strength and continuing to grow naturally should take top priority.
