@ lalalahio The other series was meant to be that way. Tae-chan was all about hiding it. This chapter is on par with chapter 3 in my opinion. Even showed a lot more. Though whether it was a dream after she smacked him with the laptop or not is up to the reader. Excited for part 2.
So it seems like it was set up as a delusion but still left with the possibility that it really happened and the guy just "believes" it was a dream as the computer was broken from when she hit him with it also tissues in the trash when he wakes up but never saw inside it before so can't tell if they were already there or from Tae cleaning up. Can't tell without a proper translation but this seems to be a prequal of sorts or at least Tae got away without getting fucked in chapter 3, which was the most explicit and hardest to argue she wasn't, probably just either got toys or anal. Reason I think this is she is acting like this was her first time, bargaining with lesser sex acts to avoid full sex. So either this is a prequel showing her first time or she somehow managed to avoid full sex up until now. That or it is really a dream and the computer is a red herring.
