If you could return to the day you met, what would the two of you do?

“Ah! Fate is unfathomable like that. Never would anyone be able to guess that such an ordinary encounter could lead to such an extraordinary future. Although our encounter that day contributed to a resplendent future, I sometimes find myself reminiscing about ordinary days.
