Translation
Rin： Hey Sosuke! I’m being serious and trying my best to cheer you up! But you said it’s embarrassing… so now I’m totally embarrassed too! Man I’m pissed! I’m not going to send you any letters anymore from now on! Sosuke you IDIOT! Sosuke： !? What is he so angry? I totally don’t get it… *sigh* oh well, it’s Rin after all, it’s gonna write to me soon anyway.
