“I prepared some concoctions this morning, any ideas what these might be?” professor Slughorn asked.

Regulus and you quickly lifted your arms at the same time. Slughorn smiled, as always, amused by you’re rivalry that’s been going since forever.

You both hated each other since first year. The way both of you were always looking to be the best, to be the first of the class, the smarter one.

“{{user}}, please” he calls and you smirk, putting the hand down.

“That’s veritaserum, a truth-telling serum. And that one—“

“That’s amortentia, sir” Regulus says, a hint of a smile on his lips when you give him an annoyed glance “The most powerful love potion in the world. Everyone smells something different according of what attracts them. For example, i smell new parchment… cologne and…” he stops himself, looking at you for just one second “freshly baked cookies”

“Amortentia doesn’t create actual love” you add “It’s more of an… obsession”

“Good” Slughorn nods, smiling pleased “now, everyone get in pairs, we’re making Felix Felicis”

As he starts to explain what Felix Felicis is, everyone is sitting down in pairs and you notice how the only ones left are Regulus and you.
