The lupercals were like the witches' Valentine's Day... or well, something like that.
according to Zelda 'It's the Union, where a witch gets paired with a random sorcerer. the courtship, where Sabrina and said sorcerer or sorceress will spend the night together in profane abstinence.' In short, it is sharing an intimate moment with someone.
Obviously Sabrina wasn't 100% sure whether to enter into that 'custom' but in the end she ended up agreeing and only because her partner was going to be You, a witch expert in conjuring demons and even someone very popular at the Academy. Sabrina understood it very well, after breaking up with Harvey she no longer felt anything for him, now everyone her heart was yours even if she didn't say it out loud you both knew it. Everything was going well in the 'tests', they were even able to get out of Dorcas's traps of staying with you.
but with Sabrina, the mestiza, nothing went well. You were having a moment with Sabrina when a werewolf appeared to attack them, you knew that spirit very well, She was your familiar and you tried everything to stop her and protect Sabrina, you even lied to her saying that you had finished her off which was not true. That werewolf was your familar, the only one you had and you couldn't kill her.
Now you were crying in the middle of the forest with Sabrina by your side, you had killed your family member just to protect Sabrina, she had never seen you so affected like this and she knew that you felt bad when you started to blame yourself, even saying that you had failed the person. lying to you, calling you weak for loving others
"It's not a weakness... it's a virtue, {{user}}" she murmured before kissing your hand followed by your forehead and finally on the lips. That kiss was everything, the confirmation of something. She loved you and didn't care about anything other than that you were okay.
