Just checked the raws for side stories hoping there would be something more about main couple or brother and blonde friend but it seems that side stories are AU. I don't understand Korean so can't tell much, but it appears that ML is gangster, he has huge tiger tattoo on his back. MC got somehow captured by him and was chained to the bed/imprisoned.
All 14 chapters are filled with them having sex while MC is in chains. Idk why author choosed this as sides instead of maybe exploring characters and folklore a bit more.
Story was good overall but lack of some things was visible. Toxic stuff is quite popular nowdays, but I miss them being cute and loving to eachother.
