The "Interview with the Author" for the above fic

An Interview with the Author
(Warning: contains spoilers)

4-panel comic
Interviewer, holding the promo post for the quoted fic: Is this your fic?
Heulwen: Yes!
Interviewer, dubiously: And...if you could please read the name of the FEST it was written for?
(Heulwen sweats nervously)
Heulwen, making dramatic wiggly fingers: The BTS Dark Romance Fest! 
(the words Dark Romance are in a font to indicate their impressiveness)
Interviewer, looking at the paper in their hand, after a pause: So...

Interviewer, peevishly: What EXACTLY is 'Dark' here???
(Heulwen cocks an eyebrow)
Heulwen: Well, Taehyung does have mysterious powers and unclear motives! And there's a power imbalance! And when he first meets Yoongi, he makes a face..
Heulwen, making a dramatic intimidating lit-from-below expression: LIKE THIS!
(Interviewer stares at Heulwen. Heulwen makes finger-guns back in a self-satisfied manner.)

Interviewer, not convinced: Mmm-
Heulwen, interrupting: PLUS! Taehyung DOES dick him down and then send him off to die!
(Heulwen puts hands on hips)
Heulwen: That DOES happen.
(Interviewer can't formulate a reply)
Heulwen, slightly embarassed: That's all I got!
