First of all, let me say this, the drama was fun to watch and decently good. However, the main theme of the story, as stated by the characters themselves, is the "Gay Concept." As the theme is a big part of the drama, that can't be overlooked when reviewing this drama.
Furthermore, we have an actual Kpop group that may or may not be using the "Gay Concept" to promote themselves, participating and acting as all of the characters in the drama. This is why, the review will be a little harsher than it would be if we're just reviewing the drama based on the story itself.

•❅✧❅✦ Story ✦❅✧❅•

The story is about two idols using the "Gay Concept" for their promotion. The two end up falling in love as they promote together.

The story itself isn't too unusual, but it was a fun watch. I was looking forward to each episode and looking forward to when they would fall in love and get together. However, the story did feel rushed, but that doesn't take away much from the drama. What does take away from the drama is the fact that we have members of the Kpop group OnlyOneOf (OOO) acting as all of the characters in the drama. OOO is known for supporting the LGBT community, but since none of the members have come out as part of the community, many people see them as using the "Gay Concept" to promote... Which is what this entire drama and manhwa is about.

It seems like the drama was trying to criticize the use of the gay concept in Kpop, however, the drama was way too short to actually achieve any of their goals. There were way too many plot-holes and not enough time to actually get to know the characters or their motivations. All I really got out of this drama was idols falling in love(?) after doing the gay concept... We didn't actually get a happy ending either, just a confession.

Lately the Kpop industry is dealing with an influx of groups using the gay concept to push their popularity. While not outright making it their concept, Kpop groups still use gay fanservice to promote themselves. Even the actors, all members of idol group OnlyOneOf, use this concept; although, OOO seems to be more supportive of the LGBT community than the other groups that are just using the concept to fanservice.

It seems like the drama wanted to discuss the issue of using the gay concept in Kpop, but there was too many plots (and plot-holes), and not enough time to actually talk about the gay concept in Kpop. It's very briefly touched upon by Eden, who is reluctant to do the concept, and even the twitter comments in the drama refer to Lion Heart as using the concept for money; but there is no real discussion on the matter. Not talking about the gay concept in Kpop is really big waste of potential since it's a topic that is relevant and brought up on the internet every day.

Also, having the members of OOO do a drama on the gay concept is a little risky. OOO are avid supporters of the LGBT community. A lot of their music and music videos are about controversial topics like sex, inclusion, and sexuality, etc. While I think it's good that they participated in a BL drama, I'm not sure if a drama focusing on the gay concept in Kpop is a good choice for them, especially because it failed to deliver on the theme of gay concepts.

This drama could have been a very good conversation piece on the gay concept, but because the drama failed to deliver an actual conversation on the topic and just used it as a background, the members of OOO are kind of dissing themselves by participating in this drama. Maybe if a member or two came out as a member of the LGBT community then things would be different, but as it stands, none of them have, and the drama failed to deliver a conversation on the gay concept in Kpop. It's kind of hard for the members of OOO to defend themselves against using the concept if none of them are part of the community.

Please don't get me wrong, I think OnlyOneOf is amazing by focusing on topics that are highly underrepresented, but if someone who doesn't know OOO comes across this drama, they will assume OOO is being hypocritical.

While the I haven’t been able to finish reading the webtoon yet, from what I read so far it’s good. It far exceeds the drama. The plot is the same as the drama, but there are no major plot-holes as of where I stopped reading. I will come back to rewrite this portion of the review if I ever get around to finishing the webtoon, but right now the English translation has stopped, so I can’t finish it.

However, I can say that the Webtoon is so much better than the drama. The drama is filled with so many plot-holes.

1. Jihoon's backstory and his scandals are not explained properly. We know he had dating scandals, but how is his ex-partner Hyunbin related to that. (They used to date.)

2. Jihoon and Eden don't really fall in love. They say they love each other, but we don't really get to see it on screen. We see more interaction between Jihoon and Hyunbin, more than we see Jihoon and Eden, so how they fell in love so quickly is confusing.

There are many more plot-holes in the drama, but these are the major ones in the drama

Putting aside the "gay concept" aspect of the drama, I really enjoyed Bump Up Business, but was too short! I feel like I have to go read the webtoon to understand the story completely. There is only 8 episodes and each episode is about 20 minutes long. It's way too short. I really liked the concept of idols falling in love, but also exploring the world of idols using Gay Business Performance. Lately lots of idols are focusing on ships and gay fanservice, so I thought the drama would focus on that.

I would love to see a season 2 of this drama not just because I want them to finish the story of the webtoon, but also because I think the members of OnlyOneOf are great actors and I want to see more of them. .. Okay, another reason is that I want to see how they handle the Gay Business Performance aspect of the drama. OOO is known for pushing the limits and representing the LGBTQ+ community, so I want them to be able to finish this drama and use it as a stepping stone in their careers and in their representation of the LGBTQ+ Community.
