As Yokoi-san is trying to listen seriously in class and Seki-kun starts doing magic tricks next to her. Yokoi-san slowly gets distracted at how good the magic tricks are...
Anyway, I should ignore him. 
Ignore him completely.
Ich sollte ihn einfach ignorieren.
Komplett ignorieren.
¡En todo caso, lo voy a ignorar!
¡Lo mismo da, le ignoraré!
Bref, il faut absolument
que je l’ignore !
Ad ogni modo, dovrei ignorarlo completamente.
Enfim, é melhor ignorá-lo totalmente.
