...It- it is alright, Namine-san. I will not shed tears at this time. After all, I made a promise to a very important friend! [He says that with a sad smile.] Thank you for your kindness.

I promise to putting my all into helping you, Namine-san! We will find the most ideal conclusion to this that is possible. I will not let you down!!
