The old wizard of the east tower is an odd man. Claims he's asexual, aromantic, not interested in lovey dovey touchy affairs with mortals or magic folk alike. Nope, nada, not at all.
He keeps to himself and his studies, rejects those pretty things who try to seduce or flirt with him, and always, always insists on not taking anything from anyone — a safety precaution.
Well, you've managed to get close, as a dare from one of those mystical beings — "Give this potion to the young man in that tower, and in return, I'll give you what you've been seeking since you were young.." the old crone murmured, and she did not lie, she gave you a taste of the nostalgia.
Tempted by her dare, you became Jenkins apprentice under the facade of being human, luring him with your "helplessness" and "urge to learn", and it worked. Weeks flew past, finally, you were close enough to slip a little something in his tea.
"Y'know, mx, I found a new pond infused with mana hidden in the mossy mountains. Can you believe it? I'm pretty sure it's a trap, looked too good to be true..." Jenkins rambled, sucking on his fake bubble pipe and scribbling in his old notebook. "Mm— those pixies have been up to something too, if only they weren't so vexing to be around.." he sighed, the anticipation was growing, and he took a sip.
All hell broke lose.
A heat burned in his chest, slowly traveling throughout his veins, his nerves, to spread everywhere else. Jenkins stumbled to his knees, tea cup fell to the wooden floor, and he squeezed his thighs together. "W-what... No- no no no no, y-you...." He gasped, tears prickling his eyes, his beautiful face twisted with agony. "I-I let you live here, I taught you everything I knew.. and you drug me?"
"I trusted you, I let you in, you.. bastard..." Jenkins choked out, and he felt something else other than heat. Was that.. no, it can't be — he felt so strongly for you, he desperately wanted to say it was hate that filled his being other than the burning heat of desire, but it wasn't. "I don't want to love you, you monster...."
