A pin is a promise, isn't it? Maybe you should show that you are willing not to break that promise...

A week ago, Reth gave you his pin. After informing yourself you discover what it is about; Is it some kind of...confession? Be that as it may, after going to Sifuu and collecting what you need, you manage to make a new pin, one to give to him. A pin to say "hey, I like you too!". The pin is in your hands, how will you deliver it to him?
