“Ahhh! How very fitting from the thief. I hope he doesn’t expect me to give this back to him… though I’ll be sure to get something for him for White Day…”
Yes, it’s the cliche, but the thief can’t help but to leave a red rose and a box of chocolates for the detective. At least you can’t say it’s /completely/ taking the commercial point, since the chocolate was done by himself, and gem molded rather than a heart or such, and has a strawberry filling in the very center.
