I... I am proud to be exceptional, Rin-san! But...I am sure that others will not take advantage of your kindness. Part of making friends is believing and trusting in them, after all! You do not have to buy things for everyone either. There are many ways to perform kind gestures!

As for the matter of smiling... it is not false if you can find a reason for it! Just try to think of things that make you smile... especially if they relate to the person you are trying to befriend!
