Lumen TV, Episode 1: Debut Dance Practice! D-7

LumenOfficial

Uploaded July 3rd, 2018

Caption: Seven days until we meet. Please wait for us!

═════ · · ─ · ˗ˏˋ ✶ ˎˊ˗ · ─ · · ═════

[The camera shakes with hollow sounds of its plastic chassis. When it stabilizes, Jinhyuk is grinning and soaked in sweat. He wears loose grey activewear and his hair pulled up into an apple shape.]

Jinhyuk: (breathless but proud) Hello, everyone! This is Jinhyuk, your MC for Lumen TV! Today we're practicing for our debut showcase. Only seven days left, so let me introduce you to the members!

[The camera jerks around with more plastic intrusion. The view pans toward the rest of the room full of wood paneling and mirrors. Audio picks up a demo version of their song on blown-out speakers and the squeak of their shoes. His sneakers blur in and out of view, the speaker getting louder until Jinhyuk's hand turns the volume dial.]

Jinhyuk, offscreen: (huffing exhale) Much better.

[Panning shot to Byungho standing close to someone else, holding up a water bottle to their mouth. He smiles at the viewer with a small bow.]

Jinhyuk, offscreen: This is our leader, Byungho hyung.

[Overlay: Byungho / Leader, Lead Vocal / 21]

Byungho: (still smiling, still holding the water bottle) Please anticipate our debut song. We'll bring our best.

[Panning a little further shows Siyoon as the one drinking. His hair is longer than the rest, tied up into a high bun with a veil of strands falling loose. He's looking at Byungho with a shadow of a smile untll he seems to notice he's in the shot.]

Jinhyuk, offscreen: This is Siyoon hyung.

[Overlay: Siyoon / Main Vocal / 21]

[Byungho withdraws the bottle from Siyoon's mouth and takes a drink himself.]

Siyoon: (wide-eyed and flushed, bows 90 degrees) Nice to meet everyone. Please take good care of us.

Jinhyuk, offscreen: (giggling) Don't worry about hyung. He's a little shy.

Siyoon: (returns a small laugh)

Jinhyuk, offscreen: But he wrote our title track! He worked really hard on it.

[The view whips back around with crunching plastic]

Jinhyuk: (grinning) And I'm your MC, Jinhyuk.

[Overlay: Jinhyuk / Main Rapper / 20]

Jinhyuk: I also wrote some stuff! Please look forward to that too.

Jinhyuk: (wide-eyed) Oh.

[Dongha and Geonwoo whip into view. Both have similar-length apple hair. Dongha's is shorter, standing up like rice shoots. Dongha stands much taller and much broader than Geonwoo, making Geonwoo look like a grade schooler by comparison.]

Jinhyuk, offscreen: And these are our babies, Dongha and Geonwoo.

[Overlay Left: Dongha / Rapper / 19]

[Overlay Right: Geonwoo / Main Dancer / 18]

Jinhyuk: (slapping Dongha's shoulder like it's a prized ham) Don't let his size fool you. He's full of youthful energy. No chance to burn it off in school!

Dongha: (laughing and rubbing his shoulder)

[The camera pans to get Geonwoo further into frame]

Jinhyuk: Ah, look at our youngest. So cute.

Geonwoo: (pouting with his cheeks puffed out) Hyung.

Dongha: See? You're so cute!

[Dongha picks up Geonwoo with a bear hug around the waist. He starts twirling, making Geonwoo shout for freedom as he doesn't receive it. The rest of the members start laughing.]

[The camera turns back to Jinhyuk as he paces the room. He stops with his back to the mirrors. The viewfinder is blinding in the reflection.]

Jinhyuk: (grinning) That's all of us! We'll wrap up by giving you a spoiler of the song and our charms.

[A thud and Jinhyuk ia backing away from the screen, peering around the camera to check visibility. Byungho and Siyoon get into formation.]

[Dongha spins Geonwoo a few more times before setting him in his spot and moving to his own.]

[Blown-out music resumes. Most members are lip syncing to their individual parts. Siyoon seems to be mouthing the whole song. They dance in perfect unison with sharp, masculine movement.]

[As the song ends, the video fades into a splash screen promoting the comeback date: July 10th, 2018.]
