After you complete this quest the ghost of a human female appears, and the following conversation unfolds:

Annalise Lerent says: Staffron...
Apothecary Staffron Lerent says: Annalise? Is that you?
Annalise Lerent says: My dear Staffron, have you forgotten what it is to love? The love that we once shared?
Apothecary Staffron Lerent says: Have I forgotten? Of course I have... I have forgotten about love, happiness... of life itself.
Apothecary Staffron Lerent says: But I do know this - love makes the heart and body weak. It can be exploited. Without your love, I have only my work, Annalise.
Annalise Lerent says: But of course I love you, Staffron. And it pains me to see you suffer so.
Annalise Lerent says: I pledge my love to you forever. Death cannot erase that, even as I am sure that you still remember your love for me.
Annalise Lerent says: And if you do not, then I am truly lost.
Apothecary Staffron Lerent says: How could you love me, Annalise? Look at me. I am not the man you once knew.

[Annalise begins to fade out]

Apothecary Staffron Lerent says: Annalise? Annalise! No, don't leave me!

[Staffron cries]

Apothecary Staffron Lerent says: Annalise... you're right. I-I can't do this. I must find another way.
Apothecary Staffron Lerent says: You there. You're welcome to take the contents of my cauldron. It was to be the second stage of my plan - amorous clothing.

1) Hillsbrad Foothills - 75,24 - North of Durnholde Keep
2) Alterac Mountain - 82, 77 - Through the cave
3) Alterac Mountain - 85, 86 - South East of Ravenholdt manor
4) Hillsbrad Foothills - 86, 26 - South East of Ravenholdt manor
5) Alterac Mountain - 89, 75 - Apothecary Staffron Lerent

This part of the quest cannot be completed after the Valentine's Day holiday is over. I left this quest in my log for about three months before deciding to get it out of the way, but Staffron wasn't there.

Clicking and using the cauldron is needed for credit for the https://vanillawowdb.com/?achievement=1695#criteria-of Nearest and Dearest and https://vanillawowdb.com/?achievement=1707 Fool For Love achievements.
