Ok so I found the raws maybe, or maybe not but it had 32 chapters so and I honestly couldnāt read it but to those that want spoilers itās gonna be down here
Our Mc and her relationship was going somewhat ok but after chapter 8 maybe around chapter 9-10? sera accidentally touches mc sister thinking sheās her and it actually happens quite often whenever sheās drunk like mc sister will be just strolling around in the street and then sera would just ambush her calling her MCs name all that blah blah,
Anyways seraās sister did approach mc sister to which id guess maybe asking her to help make mc and sera drive a hole in their relationship or something (idk im just assuming) but in the end mc sister said no.
And around chapter 32 I believe mc starts to think the worse that sera IS really using her to put out her frustrations with sex so u could say it starts turning a bit toxic just what I kinda expected from this author
oh side couple here too itās between seraās sister and her secretary, itās like a s&m play but in my opinion I think theyāre lowkey somewhat the healthiest relationship in the manhwa currently but do correct me if Iām wrong bc I was just observing the panels. Since around the end the sister did care for her
