" 사랑해요 [sa-rang-hae-yo] " means " I love you ", " 좋아해요 [joh-a-hae-yo] " means " I like you "
And " 싫어해요 [shilh-o-hae-yo ----> shi-ro-hae-yo] " means " I dislike you " and " 미워요 [mi-wo-yo] " means " I hate you "!
" 요 yo " is a term for politeness, you can omit it if you're close to the person or you are insulting the other person ( very awkward advice :| )!
