i feel good today, 오늘 하루 기분이 좋았는데 but my friend ruined it!! so i am annoyed.( or that sucks!) or it sucks that my friend ruined it. 친구라는 놈이 망쳐서 짜증남. i hope that it is helpful ^-^

놈 fella =]

it means ' i did feel great but who my friend spoiled that feeling and it was sucks'

well, i'm not sure with this, but i hope it makes sense.. today's mood is good for an irritable guy ruined my friend?.. hehehe... not so sure...
