Apparently, this involves the same struggles as in 'Yoru wa Tomodachi'. Edit: Just read this, and yes indeed, the seme gets pulled into the uke's kink, when it's not his natural inclination, and starts to lose control of himself as a result. I much preferred this to YwT, though. I found this manga beautiful. The art was simple, yet wonderfully evocative, and was a perfect match for the dark and deep subject matter. 4.5 stars.
