suki desu if you want to say "I like [something]", then you say 'watashi/boku WA [something] ga suki desu or if [something] is already the subject then just suki desu, or if what you like or just you are the subject then [something] ga suki desu.
'Sore ga suki desu.'
For "I like you" the closest equivalent is "suki desu". A little stronger version is "dai-suki" which is, "I like you a lot."
hamu ga suki desu!
Kore ga suki. This + ga + like
"Hon wo suki desu."
