There really is no plot. You have the bottom who’s so much of a workaholic that his fiance or gf left him. But he also currently hates his job. Then you have the top who’s both weirdly sentimental about a building but also a raging sadist/masochist. Who loves being a punching bag for anyone willing. The bottom is trying to force the top to sell his building to them. The top already admitted to lying about being willing selling his building the first time they made a deal and yet the bottom took that as an invitation to use his body as currency. Its just watching paint dry. Nothing interesting has happened.

not complaining, like the plot & art actually. this chapter was just a little bit unbearable
