I think the author felt the pressure of people wanting to see them having sex. I agree with you, however, in the previous chapters we saw that he cannot erase him because the political party doesn’t want to be associated with any scandals.
On the other side, it is obvious that the guy is not enjoying the sex and he is straight. I would prefer to see Incheol trying to masturbate to see if he can handle this or not. Maybe author needed a shock element for Incheol (he will probably discover that he enjoys this and he will start to question himself etc.). Still I think next chapter has the potential to define how the story will proceed.
I would really want this story to be different and see characters acting like their age and position.

Everyone seems to like their first time, but I didn’t at all. It’s not surprising, considering the smut in her previous work was also underwhelming so I was prepared somehow.
The bare-minimum smut we had before was much better it was sensual and erotic, fitting perfectly with the atmosphere and art of the work. But now, with chapters of back to back smut, it just looks really cheap.
I’m also so tired of authors always making the uke forced to have sex or raped, no matter their personality or financial status. I expected so much from this author in terms of smut, but just like the poor weak uke who has to sell his hole for money, Incheol, a strong, financially independent politician, has to sell his hole and is forced to have sex with a nobody he could easily erase given his position. It’s basically the same as other BLs, just in a different font.
I’m not expecting much from the romance aspect either, because in her previous work, despite the story being fluffy, the smut was underwhelming. The uke, also a straight, older guy in uniform, didn’t seem to enjoy the sex at all, and he never seemed to be in love with the younger guy.
I don’t think Pyeonghwa and Incheol will ever have emotional chemistry. Kinda disappointed that their toxic dynamic is just for the kinks, not something I would bother to be emotionally invested in.
