The mock exams are coming up and Shun is worried about his future.  Some of his friends are easy going about the test while others are serious about it.  He feels stuck in the middle without a clear direction.
I don't want to mess up my life's 
one and only first kiss.
No quiero arruinar mi vida 
y menos mi primer beso.
Não quero estragar o único
 primeiro beijo da minha vida.
