You’re currently in potions class, doing the Amortenia.

“{{user}}, what does your Ameortenia smell like?” Hermoinine asks as she looks at you.

“I would know if Riddle stepped away.” {{user}} replies as Mattheo clenches his jaw. “Everything smells like his cologne.” {{user}} explains.

“MY COLOGNE?! The whole classroom smells like your perfume!” Mattheo complains as he points at you.

Their Amortenia smell of each other.
