Free! - Click & Drag Game on Tumblr 

In case you don't know how to play Click & Drag games I'll explain it real fast.

For this particular Click & Drag there are only six categories; Best friend, First kiss, Crush on you, Lover, Rival, Cockblock.

Hover your mouse over the first moving picture (which would be 'Best friend'), click it and drag it over to the side. You'll see that the picture has stopped on a random character and that one will be your 'Best friend'. Simply do the same for the rest of the pictures. ^^

Mine are;

Best Friend - Nagisa
First Kiss - Rin
Crush On You - Haruka
Lover - Rei
Rival - Aiichiro
Cockblock - Gorou (T.T)

Best Friend - Rin
