(In this Slughorn is mean)
"Move out of the way!" Y/N said as she dashed down the hall to her Potions lesson, which she was already late for.
Running through the dungeons to Slughorn's lesson. Pushing the door open and silently coming in while Snape was talking and writing on the board at the same time.
"Thank you for joining us, Miss Y/L/N." He said this as he turned to face Y/N, who was flushed yet afraid.
"S-sorry for being late, sir, I-I woke up late and-"
"Fifty points from Gryffindor, and detention with me at 7:30." As he sits at his desk, he says.
Y/N walks over to her workstation next to her best friend, Y/BF/N, still stunned by what has just occurred.
When she hears his voice, her face turns downright hostile. Sirius and Y/N have been working together since their first year. Nobody knew what they were up to. But Y/BF/N and James have this theory that they love each other but don't know how to tell each other. They would never acknowledge it if they were in love.
"Shut it, Black." Y/N tightened her teeth as she glanced at Sirius.
"Why don't you say it louder, Y/N," Fred remarked, winking at her.
"Sirius Black, I told you to shut it!" Y/N stated as she rose from her seat. Sirius tracked her every step.
They began to argue loudly, their faces dangerously near one another.
"ENOUGH!" Slughorn yelled, prompting the two to halt and glance at him. "Both of you, you have detention at 7:30 in my room!" As he continued to teach his potion lesson, he said.

After dinner, everyone made their way back to their dorms. Except two. Y/N and Sirius began their journey to Slughorn's room.
When they entered, they were met by Slughorn, who stood by the door with his arm crossed.
"I want you both to put this-" he paused in the middle of his statement, taking his wand from his cloak. With a single flick of the wand, four massive stacks of papers materialize on the table. "In alphabetical order." He says this as he walks up to the door and slams it shut once he's out.
"Bloody hell," mumbled Sirius as he sat in a chair.
"Well, aren't you at least going to help me with this?" In annoyance, Y/N asked Sirius whatever she wanted.
"Why should I?" As his brows knitted together, he asked her.
"I swear to Godrick, I'm going to hex you into the next generation, Sirius Black! Y-you are truly great; you always rely on others to do your trash. No, so far that I-" She was interrupted by a tall figure kissing her.
She tightened up throughout the kiss but quickly relaxed. Their lips moved quickly and hungrily in a kiss full of anger. Sirius brushed his tongue over her lower lip, requesting admission, but she refused, teasing him. Sirius nipped her lower lip, gently but forcefully enough to make her gasp. Taking a gamble, he inserted his tongue into her mouth.
They both began fighting for territories but were interrupted by Slughorn's arrival.
"WHAT ARE YOU TWO DOING!?" He screams at the two.
"Well, sir-" Y/N begins but is cut off.
"OUT!" Slughorn screams.
"But-" says Y/N.
"OUT!" He yells again, leading the two to flee.
Running the halls together, giggling. They quickly arrive at the Gryffindor common room.
"Merlin, did you see his face?" Sirius laughed, clutching his gut.
"Priceless," Y/n says, laughing as well.
"I believe he was jealous of us," Sirius whispered, grabbing her waist and pulling her close to him.
"Now, why is that?" She inquired as she wrapped her arms around his neck.
"Because no one has ever kissed him, and seeing us..." Sirius said this while continuously placing small brief kisses on Y/N's lips.
"Makes him jealous." She stated this before pressing herself against him to intensify the kiss.
They have no idea that James and Y/BF/N witnessed their shared kiss in the common room.
"You owe me five galleons." Y/BF/N addressed James.
"Here," James said, handing the money to the happy Y/BF/H/C.
"Say you'll be mine," Sirius murmured, drawing back.
"Of course, Sirius." While hugging him, Y/n said.
