Seme touched the uke without his consent (in the 1st chapter) and he did that later on as well, fucked the uke forcefully even though the uke wasn't agreeing with him which means he basically raped him. He rejected the uke's love confession(uke has the usual stockholm syndrome every other uke's in some mangas tend to have you know) after raping him and still had the audacity to order the uke (telling the uke to not let himself be touched by others or go out with other people ). He treated the uke with no respect (treating him like a toy for his own enjoyment) and expected the uke to always listen to him. I freaking hate the seme. Such a horrible, disgusting psycho. I also hate how the author tried to justify the seme's actions at the end by completely changing him. Yeah, there is always a second chance for everyone to correct their wrongdoings (which takes time) but that doesn't mean their actions should be forgotten and forgiven so easily. Pretty sure if the uke disagreed with the seme's words at that time, seme would've gone full on psycho...
