Himeko saves a first-year student, Jin, from some punks, and he falls head over heels for her. In order to get him to stop hounding her, Himeko tells Jin that she's already got a boyfriend... Bossun! Now all she has to do is prove it to him...
I think you should really explain the 
situation to Bossun and have him help you.
La única forma es pedirle cooperación 
al Jefe explicando la situación, ¿no?
Deberías explicarle la situación 
a Bossun y pedirle que te ayude.
Eu acho que você deveria explicar a
 situação ao Bossun e pedir ajuda a ele.
