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...
S-Sorry, it's nothing!
!آ-آسف، لا شيء
E-Entschuldige! Es ist nichts!
¡Lo siento, no es nada!
¡Lo siento, no es nada!
Oublie, c’est rien !
S-Scusa, niente.
D-Desculpa! Não é nada!
Извини, ничего!
