Haruhi-chan/Heartwarming

From Haruhi-chan:

 * Haruhi's slow, happy smile in episode 19 when her beliefs in Santa Claus are vindicated.
 * Episodes 15 and 22. Seeing Achakura and Kimidori interact makes  in episode 24 that much more of a Tear Jerker.
 * Any time Nagato and Achakura make up after a fight. D'awww.

From Churuya-san:

 * "Nothing bothers me when I'm eating smoked cheese."
 * Kyon giving Churuya smoked cheese for christmas. Subverted when a mouse tries to steal it. But then it gets chased away by Shamisen. Who then proceeds to eat the cheese himself.
 * When Churuya gets to see the first cherry-blossom bloom.
