Effy isn't getting along with the girls at school, and Kris has a plan to fix that. Meanwhile, Ingrid is annoyed that Yuuto fails to notice her advances, and tries to get him to realize that she's a girl.
Anyway, you get so hot when 
you make glass, you know?
Jedenfalls wird einem total heiß,
wenn man Glas bläst, was?
Hace calor cuando haces vidrio, ¿no?
Hace calor cuando haces vidrio, ¿eh?
Tout de même, il fait chaud,
quand on travaille le verre…
Comunque sia, viene proprio caldo
quando lavori il vetro, sai?
De todo modo, esquenta bastante
quando fazemos vidro, não é?
Кстати, ты заметил? Когда делаешь 
стекло, так жарко становится.
