Basically in chapter 11 DG is shown watching jiwon's broadcast and he seems fine after their sex session so DG let's out a sigh of relief
The next day jiwon calls DG to a club room (?) at their university and they start having sex there but then Jiwon's friends start knocking on the door and try to get in but they end up giving up and walking away to get the key to the room so jiwon and DG panick and run out
Then later DG and Jiwon drive to Jiwon's apartment and DG ends up fascinated over seeing his broadcasting set-up, like his mask and stuff, and then they go into his bedroom and have sex. When they're done DG gets sleepy and he smiles really cutely so Jiwon lets him sleep in his bed and then when DG wakes up he passes by the room where Jiwon live streams and notices that he's talking, aka holding a live broadcast
All this might not be entirely correct but I can't read Korean so I'm just guessing that this is what happened based on what I saw

But DG really looks like Xiumin and Jiwon looks like Chanyeol from EXO I'm shaking
Anyhow, I read the raws and oh LORD I'm looking forward to reading them in english
