The Bad Boy's Yandere

He looked at me, no wait-he didn't just look. He gazed into my soul like the devil. I gulped and felt the heat rise to my cheeks. Then he cracked a smile,"You're a weeb aren't you?"
I was slightly taken aback by the random question and also slightly annoyed,"Um.. no. I just watch anime."
He ran a hand through his hair,"Makes you a weeb."
I let out a breath suppressing a glare,"N-"
He cut me off by holding his hand up in my face. I shut my mouth even though at this point I wanted to kick him in the balls, and a lazy smile spread across my face at the thought of him clutching his crotch in pain and his face contorted into pure agony.
My smile dropped when his hand went to my hair as he pet me,"Good weeb. Now that I've seen what you can do," referring to me saving his life,"You are familiar with the term yandere?"
I nodded slowly, wondering where he was going with this.
"Good cause from now on, you can call me Senpai."
What???

Yandere (ヤンデレ) is a portmanteau of two Japanese words yanderu (病んでる), meaning to be sick, and deredere (デレデレ), which is defined as strongly and deeply exhausted, infatuated, moonstruck, head-over-heels, or lovestruck, but in this case used for "lovestruck."
