Korean Phrases for Replying to an Idol's Private Message
The private message apps idols use do not translate themselves. A notification lands at eleven at night, it is three lines of Korean, and the reply box is right underneath it. Most international fans read the machine translation and then type back in English, which works — but the Korean lines are short enough to learn in one sitting. 오늘도 고마워요 (oneuldo gomawoyo), "Thank you for today too," and 밥 잘 챙겨 먹어요 (bap jal chaenggyeo meogeoyo), "Make sure you eat properly," carry most of what fans want to say.
- Thank them: 오늘도 고마워요 (oneuldo gomawoyo), "Thank you for today too."
- Look after them: 밥 잘 챙겨 먹어요 (bap jal chaenggyeo meogeoyo), "Make sure you eat properly."
- Tell them to rest: 무리하지 마세요 (murihaji maseyo), "Don't push yourself too hard."
- Say it back: 저도 보고 싶어요 (jeodo bogo sipeoyo), "I miss you too."
- End the night: 잘 자요 (jal jayo), "Sleep well."
How do you answer a message app in Korean?
The thread has a rhythm — they say something small about their day, and the reply that fits is also small.
- 오늘도 고마워요 works on any message, which makes it the safest first Korean line you ever send.
- 밥 잘 챙겨 먹어요 when the message mentions rehearsal, a schedule, or a flight, because skipped meals are the running theme of those posts.
- 무리하지 마세요 on the nights the message sounds tired, and it lands warmer than a plain "rest."
- 저도 보고 싶어요 only as an answer to 보고 싶어요, never as an opener — the 저도 is doing the work.
- 잘 자요 to close, since most of these threads end with somebody going to sleep.

What do Korean speakers say back?
The messages that come in are shorter than anything in a fan thread, and they ask questions.
You: 오늘도 고마워요 — oneuldo gomawoyo — "Thank you for today too."
Them: 밥 먹었어요? — bap meogeosseoyo? — "Have you eaten?"
You: 네, 먹었어요 — ne, meogeosseoyo — "Yes, I've eaten."
Them: 저 이제 자러 가요 — jeo ije jareo gayo — "I'm going to sleep now."
You: 잘 자요 — jal jayo — "Sleep well."
Them: 좋은 꿈 꿔요 — joeun kkum kkwoyo — "Sweet dreams."
밥 먹었어요? is not really about food. It is the standard Korean way of asking whether someone is doing alright, which is why it turns up in these threads more than any other question. For the texting habits behind the rest of it, see Korean phrases for texting on KakaoTalk.
What usually goes wrong in a reply?
The first slip is copying their speech level. These messages are often written in 반말, the casual form, because that is how someone talks to people close to them — but mirroring it straight back reads as over-familiar from a stranger. Keeping the -요 ending is what Korean fans do, and it never sounds cold.
The second is 수고했어요 (sugohaesseoyo), "good work." It is a fine sentence between colleagues, and slightly off pointed upward at someone you admire; 고생 많으셨어요 (gosaeng maneusyeosseoyo) says the same thing with the respect built in. For the vocabulary of a live broadcast, where the same lines get typed into a comment box instead, see Korean phrases for a K-pop idol live stream.
Say it out loud, not just in your head
These lines look like typing practice, but they are the same sentences that come out of your mouth at a fan sign, in a video message, or when you finally meet someone from the group chat in Seoul.
