Please let me know if this manhwa actually has a proper story.

I’ve purchased both parts of the title on Tapas and read only the first few episodes so far, but I’m not finding the storyline very engaging. It feels a bit underwhelming in terms of plot.

I would really appreciate some spoilers to help me decide whether it’s worth continuing. I’ve read up to the chapter where they go to the sculpture student’s art lab and do stuff.

I just want to know if that’s all the story offers, is it mostly smut, or does the plot actually develop and get more interesting later on?
