감사합니다! Thank you for explaining Cyan! :)

Hm, there are some difference between those sentences.. First, 사랑해 is unformal word and it is called when someone older person say to younger person. If you have a bf who is older than u and he is Korean, he may say 사랑해 미치.. And 사랑합니다. is formal. this will be called when younger person say love to his girl friend or who was loved. In fact, most of people who have older bf or gf, they say 사랑해 more than 사랑합니다. But,, very formal and polite ppl say 사랑합니다. p.s 사랑합니다 is more heartfuler than 사랑해. 사랑해 is too common and impolite. i like 사랑합니다 more
