Unfortunately it's hard to demand good action scenes in romance-based story unless they are a big project. In fact a lot of BL's artist commissioned another artist for the action scenes because truthfully fight scenes are harder to draw than sex scenes lol codename anastasia is one of the example, which is why the fights look great because they work with multiple people. Such things need budget and it's usually done for more popular works. Since this manhwa is mostly focused on the romance unlike action packed like hunters gonna lay low / death delayed by hunters will, they won't waste another resources for the action scenes and just focused on the romance. It's not worth it and they definitely won't get enough profit to cover for it.
There are some BL artists in the back of my mind that I can name who are good at both the romance and the action scenes like roses and champagne artist, the taming, perfect buddy (although its not action packed, the artist is so good at action-like composition) etc. We just gotta be grateful they already make the art pretty for the romance

..I was seriously hoping to see some badass action scenes but it was over with three panels? Thats just freaking dissapointing.. I dont know what it is about new hunter/guideverses that the action and fight scenes are seriously lacking. Ugh I miss "death delayed by hunters will" and "mission save the hunter" types (I am letting them marinate..)
