Nishikata receives his first cell phone and can't wait to play tricks on Takagi-san.
He sends her a scary video to frighten her, but it doesn稚 quite work. 
As usual, Takagi-san has the upper hand when it comes to teasing...

!لا، لا شيء! صدّقيني

¡No es nada! ¡En serio!

No, non c'è niente! Davvero!
Não, nada. Verdade!
Не-не-не, нет!
Ничего, правда!
