@RaizelX Its the MCs junior (at the same company they work at) who likes MC, MC has a crush too. He finds out that she is a huge slut addicted to sex and particularly gangbangs and she notices him in the crowd watching after he followed her after work because he was worried about her. That's it for now....
@poke-- I have no idea what you are talking about Who/what bullet? Did I missing something, even the newest update doesn't show anything, just more sex.
I think poke-- is referring to the MC not being married to or being in a relationship with Hime(What the other men call her, maybe a stage name?)... like the other NTR story he linked by the same artist.
Regarding the story; is there any indication that she likes the MC other than the looks she gives him while having sex with other men?
She has no real dialogue that I can tell besides calling the MC a pervert on page 9 and on page 10 that that day was her alone day( not sure about the translation for that one). The rest is just random moans
She could just be embarrassed that her senpai found out her secrete and not really have any feelings for him.
