I dunno. This is the latest chapter where they have sex. But Param storms out the apartment afterwards and starts crying. I think he might regret it. But still doesn't change the fact he did it.
Tbh I think it was a pity shag (and lust) because Mr Han went on to talk about his past love that betrayed him after Param initially tried to reject/ brush his advances off.

Param initially rejected him but gives into his desire. Param talked about wanting to hurt Mr. Han for messing with him and he thinks sleeping with him will be revenge??
From what I can tell at the end of the chapter Param does not regret it. He was trying to reason with himself about why he actually slept with Mr. Han. Param just comes to the conclusion that bc he wanted to ┑( ̄Д  ̄)┍
Well...
