looking at the prev chapters, we know that castillo and lippe has actually some quite of relationship ( which may be not romantic, and maybe enemies ) and my theory was that, what if castillo has access towards what’s had happened in the prev life, maybe he know how lippe’s life turn upside down that one day when her brother ( or father(?) went missing and was found dead. That made he pique interest in lippe, also that handkerchief scene too. Maybe because he’s the royal blood line, he has some power to know or the goddess that give lippe the chances to return back tell him or let he know
