I'm still interested in the regression part but wth the ML is so trashy...

there's regression?? I just jump in ch26-27 to see it it's good and I might just marinate this one a bit longer before reading from the start

According the last raws uke indeed regressed in time, I think in the past time line the misunderstansing wasn't cleared up, so ML treat him like trash, raping him, imprisonnhim, breakingbhis ankle. Then ML got killed /stabbed/ and die, then uke comit suicide and come back in the time. (Raws are till ch 40.)
