Hysteria (Yandere!Tsukishima x reader)

H Y S T E R I A:

Everyone knows that Tsukishima Kei has been, and will always be an indifferent asshole. He is plain out rude, unnecessary, and sarcastic. He goes out of his way to say something negative and to put down and make fun of people. Many wonder how Yamaguchi even tolerates him.

But what happens when a new girl transfers all the way from France, with an unwavering smile?
Y/n Clémence is a fifteen-year-old girl who transfers to Karasuno a few months into the school year. She becomes quite popular from her angelic looks and the fact that most people consider her the happiest person in the world. She is sweet and kind to everyone, never seen without a smile. It is almost impossible to not like her with her honey voice and the way she speaks to anyone making them feel truly appreciated. Not impossible for Tsukki though. He doesn't like her one bit.
But why does he always find himself running away and towards her at the same time?
