One day, while attending school with Ki, Keika encounters a young woman at the university who is able to see him and seems interested in being friends. She has a passion for teaching, but her lessons are not going well and she is struggling to gain the respect of her students. However, Ki suspects the woman has a very different reason for pursuing a frienship with Keika.
It's been my dream to teach 
the pleasure of learning.
Es war mein Traum, ihnen beizubringen,
wie toll lernen ist.
Siempre ha sido mi sueño
enseñar la dicha de aprender.
Siempre ha sido mi sueño
enseñar la dicha de aprender.
C’était mon rêve de transmettre
la joie d’apprendre.
Era il mio sogno, trasmettere
il piacere di insegnare.
É o meu sonho ensinar
o prazer de ensinar.
