8 Korean comments to leave on your idol's posts (and what fans actually write)
Korean fan comments have their own conventions, and a lot of them come down to honorifics. Idols are strangers you admire, so fans write to them in polite 요 speech, often with the honorific 시 slipped into the verb, even when the idol is younger than they are. Writing 사랑해 instead of 사랑해요 is not wrong, but it reads as a child's comment or a very casual one.
These eight phrases cover the posts fans comment on most: a new photo, a performance, a comeback, a hiatus, an exhausting schedule. All are in polite 요 speech, and the notes mark where Korean fans add an honorific or a name.
-
사랑해요.
saranghaeyo.
I love you.
Polite 요 speech, and the most common comment under any idol post. Korean fans add the member's name or 오빠 / 언니 / 누나 / 형 in front depending on their own age and gender relative to the idol, and skip the title when they are older.

오늘도 멋있어요.
oneuldo meosisseoyo.
You look amazing today too.
Literally: Today also cool.
The 도 (also) is the fan touch: it says this is a daily fact, not a one-off. For a feminine 'pretty' swap in 예뻐요; many fans use 멋있어요 for anyone on stage regardless.

수고하셨어요.
sugohasyeosseoyo.
Great job out there.
Literally: (You) took on hardship (honorific).
The comment after a concert, a music show or a long livestream. Note the honorific 시 inside it: fans write 수고하셨어요, not 수고했어요, because the plain form is for someone your own age or younger.

항상 응원해요.
hangsang eungwonhaeyo.
I'm always cheering for you.
응원 is the word for cheering a team or a person on, and 항상 (always) is what makes it a fan's promise rather than a passing compliment. It is also what you write under a post announcing bad news.

밥 잘 챙겨 먹어요.
bap jal chaenggyeo meogeoyo.
Make sure you eat properly.
Literally: Rice well take-care-of eat.
Korean care sounds like a parent. 챙기다 means to look after or not forget something, and fans use it about meals, sleep and coats. The more deferential 밥 잘 챙겨 드세요 (with the honorific verb 드시다) reads as more grown-up.

컴백 축하해요.
keombaek chukahaeyo.
Congratulations on the comeback.
컴백 is the loanword for a new release, and 축하해요 is the everyday congratulations. Add 대박 (daebak) at the front and it becomes 'what a huge comeback'.

보고 싶어요.
bogo sipeoyo.
I miss you.
Literally: (I) want to see (you).
The standard comment during a hiatus or military enlistment. Fans stretch the vowel in writing, 보고 싶어요오오, to make it sound like a wail; that is affectionate, not a typo.

아프지 마세요.
apeuji maseyo.
Don't get sick.
Literally: Do not be in pain (honorific).
Posted when a schedule looks brutal or a member looks tired. -지 마세요 is the polite 'please don't', and it is the phrase Korean fans reach for far more than 'take care'.

Two habits make a comment look native. Put the member's name first, with 아 or 야 after it only if you are older than them and want to sound close, and otherwise plain. And finish with ㅠㅠ for anything emotional or ㅎㅎ for anything cheerful; a bare sentence with a full stop looks stern in a fan cafe.
