a little explanation about raw:

" Shingo asked Kagami's brother why the smell can disappear. The reason is about Kagami's heart. If he does not like or want, his smell will disappear. Then shingo came back home to make sure about this answer. He find that Kagami has disappeared the smell. Then Kagami tells shingo he need to live in the foreign country for half or one year because he allowed the director to join his film. That's why Kagami clears up his luggage. At last , kagami asked shingo if he want to go together. However, shingo did not answer this question. He said the want to make love with kagami and ask him to remember his smell because they can not see each other for a long time. I just guess shingo thinks that kagami does not like him so he may disappear when kagami goes abroad.
