For those that need subtitles, I have translated the whole video for fellow fans (I'm Korean so u can trust these): Beginning: Chanhyuk: Re-Bye, what are you? What kind of song are you? Even I don't know... Chanhyuk: (talking about the title) "Re" means "again," and "bye" means a farewell, so..."bye once again"? 0:52 C: With this album we wanted to show you a different side of AKMU, and... Suhyun: After listening to Lee Hi unnie's "1,2,3,4" I begged him to write a song like that for me, so he wrote this song on the spot (laughs). Lee Hi: When I heard that they were inspired thematically by my song, I couldn't NOT come (laughs). If sajangnim (her boss, aka YG CEO) sees this, he'd probably be like (imitating yang hyun suk's voice) "lee hi, you should be working on your own choreography, what are you doing studying AKMU's choreo" 1:31 C: (after licking fake spilled blood) It's still fresh... C: We're playing the role of two detectives infiltrating a theater performance to find the culprit of a mysterious incident. 1:46 C: The name is Chanhyuk, Detective Chanyuk. C: We're the world's smartest detectives. S: Yes, the very smartest. 1:54 S: I was acting with Sungkyung unnie, and I was quite scared. There was a scene where she gets irritated... (they show the scene) S: omg I think I'm going to cry (laughs) S: I almost was in tears...I filmed this scene and was hiccupping outside S: Why am I so nervous...? C: As her older brother I suddenly felt protective (Suhyun giggles) C: ah...my heart hurts...(changes tone) but she needs the discipline...when our parents scold her, she gets away with aegyo! C: (sarcastically) the fact that I could only watch and not do anything was frustrating, and I wanted to run over. I was suppressing the anger. (this is all sarcasm, which is why Suhyun is giggling the whole time). C: I'm going to raise her to be strong. C: In the MV, watch Suhyun carefully. C: Sajangnim (YG) likes choreo that everyone can follow easily, so he created the moves for the main "Re-e-e-bye" chorus, and then I created this wave for the higher "Re-bye" part. C: We hope you enjoy the song, S: And please capture cute shots of us! C: Please enjoy and look favorably on us in the music video, S: Yes, enjoy the video, and re-bye!

I can't handle how attractive and gorgeous they are. This M/V was brilliant. That plot twist! Great song, everything! This comeback is one of the best.

such a good hair color for Chanhyuk

HAYIIIII WAS THERE TOO . AWWWWW

LOL LEE SUNGKYUNG "MICHEOSO!!???" SOOOOOO BAEK INHA😂

yg please i need eng sub 😭

Soohyun is so gorgeous. Chanhyuk is handsome as well. These two so talented, I lobe them so much

Re bye I mean lee hi looks so young and pure here without makeup. Love their new songs and they seem to have fun filming as always. The brother finally has a main role and cool not funny one I'm glad. Although I love him in his funny roles too.

lee hi so supportive.. i love their friendship...

Lee Hi is more beautiful without make-up :')

Who fall in love with chanhyuk too?!!

Lee Hi is so friggin cute without makeup i want to go hug her~

동생걱정하는 오빠ㅠㅠ좋아할수밖에없다..

omg so handsome he is .. suhyeon is pretty ..

lee hi teach me your skin secrets! How do you look so beautiful without makeup!😍 I love Akmu they are so cute and I love the support hayi gives them! 😍😍

SUHYUN IS SOOOO CUTE

can we just appreciate hayi supporting akmu there? 💕 this is the reason why i love ygfam

came here after watching ikon and winner. our talented akmu siblings.

She's so pretty

ㅋㅋㅋyg멤버들은사장님성대모사가ㅋㅋㅋㅋㅋ

Hayi looks 10 years younger with little makeup, how can she be so beautiful. Her impersonation of Papa YG was on point! 👌

hahahahah this is like Baek InHa and Seol all over again~~~ 😄 Suhyun really looks like Seol (Kim Go Eun)

The intro gave me mad chills XD I loved this song.

It's always worth the wait for their music 💕

Nation's Siblings fighting!

lol look at lee hi impersonating yg. this song is so good, ive been put it on repeat since it came out.

Cant understand a thing, but im smiling all throughout the video 💖 cant wait for eng sub

lee hi imitating YG Appa ㅋㅋㅋ

Thought Baek In Ha might get a chance to speak... :P (The feels when you are this early to a 'YG' video is exemplary

Watch the whole video with clearly no idea what they are talking about... Worth it anyways!

Am I the only who thinks this is Detective Conan themed? Chanhyuk is wearing a suit that's similar to Conan's when he investigated and they also wore uniforms that were similar to Shinichi and Ran's at 3:08

The only thing I understood is that Chanhyuk said something along the lines of "Re means again, and Bye means goodbye(he said the korean word for it, I think), so Re-Bye means 'Goodbye again'." Also, I absolutely love Suhyun's violet-y ombre hair. And also, was that Lee Hi?! Is she not wearing make-up? She's gorgeous!

수현언니두 사랑해유 ♡
