No that Sekai bitch was the villain of the show. She hooks up Makoto with Kotonoha then seduces him by letting him practice on her.
She turned that innocent boy who just wanted a girlfriend into a sex addict and when he finally comes to his senses and tries to go back to Kotonoha, the bitch kills him.
I hope Sekai is burning in hell where she belongs!
