Eros tells Fusaaki that his house needs more life, so he suggests getting pictures or flowers...

Fusaaki: Do you know how to take care of flowers? Because I sure as hell don't. 

Eros: Well. You need water, for starters!

Fusaaki: 

Fusaaki: No shit. 

Eros: Yes!

Fusaaki: It's entirely new to me that flowers run on water and sunlight. Thanks for pointing that out.
