No connection at all that I know of. The -ku in Candiku is just the combining form of aku I, me, my. Before a verb it's I, joined on to the end of a noun it's my, joined on to the end of a verb it's me.

For example: pacarku (my boyfriend/girlfriend), sepatuku (my shoe)
Aku sangat suka AWAD. (I like AWAD a lot)
Menyuratiku dong. Go on, write to me.
Dia tidak mencintaiku lagi He/She doesn't love me any more.
