Upon seeing Gaven, the tall and burly Delara immediately greeted him with overflowing enthusiasm, "Mr. Gaven, you truly are a rare cocktail genius. It's unimaginable that you could create such a unique Heart-Viewing Cocktail after studying mixology for just a few days, even helping me recover my lost memories. I owe you a favor. If you need anything in the future, just let me know."
Recovering lost memories?
The Heart-Viewing Cocktail has that kind of unique effect?
Even Gaven himself was a bit perplexed, yet his expression revealed nothing. "There's no need to thank me. What I planted in you was merely a seed of emotion. What flower it blooms into, what fruit it bears, that's all up to you. I suspect that recovering your lost memories was entirely due to you breaking through your mental block and being able to withstand the pain that was previously unbearable, not my doing."
Such things are inherently ambiguous; any explanation could be the right one.
