Old Crushes, Nasty Feelings

XD This popped into my head a while back. Since Seiichi is the only one to know about Tsuki's past crush on the Gryffindor, I imagine Seiichi being a tad jealous of Basil when Tsuki and him start dating. Here is Basil, saying his final goodbyes to the rest. He says good-bye to Tsuki, and then Seiichi. Seiichi, being the jelly boyfriend simply puts on a smiley face and says goodbye to him, but inside he's ticked.

"I wish you a lot of luck, Basil." Seiichi gritted through his teeth as he shook Basil's hand and smiled. "Hope you're successful. Also, I wish you luck in finding a girl. Hopefully, she isn't taken by someone. After all, that might cause you problems, right?"
"Um... I suppose." Basil replied, wondering why Seiichi's grip on his hand was extremely tight. Tsukihime, watching the scene, turned crimson red and covered her face. Embarrassed written all over her face. She also knew the others were now watching them and this made her even more red.

XD Making Seiichi jelly is fun~
