Yeah you know what else sweets and sugar did to you? Give you bad teeth. So like in every other class, Yoongi remained seated in his seat while he waited for the Professor to tell which potion they were going to work on today.

Amortentia? He vaguely knew that name...oh right, it was the love potion. He had only been in love once. During his fourth year in Charms school. Ah he had had the biggest crush on the top sixth year elisabeth. Ah the memories~ she never knew he had a crush on her though. Merlins Beard if she ever found out... As for here? He didn't particulary like someone at this school. At least not that he was aware of it? That was why he frowned when Norah's face suddenly popped in to his mind. Nope, just friends...he didnt have feelings for her...he thought..no?ugh this was confusing already and class had only just started.
"The Weasley shop sells them" that was the only information he could give. He knew that it caused fake love or obsession but others already told that.
