Every once in a while, each member of the Host Club would reflect and realize how much Tamaki starting this club and inviting them in has affected them.

Mori was able to see Honey at his happiest each day. Kyouya has somewhere to be where he enjoys himself and can escape his father. And for Haruhi, she had Tamaki to thank for a plethora of things.
Not that they'd ever admit this out loud.
