I like in this one how even when Ren moves several meters in 3 seconds he's (as it says in the verrry little box) 'still elegant'.

I have a lot of favorite moments!
Last volume (200) when Kyoko realises she's in love with Ren.
Ren's posessive moments xD
Kyoko's strong acting
Ren's manager.. all the 'mobile' moments and him laughing at Ren (he figured Rens feelings out somewhere in the start of the manga)
And too much more to sum up.
