You can put it that way, but then again what counts as true "choice"? It's not like Mitsuru went to Kouichi and was like, "hit me, burn me and force yourself on me"--and no, it doesn't matter that Mitsuru was aroused, it was still nonconsensual. Kouichi has manipulated him into thinking that he's "dirty" now, that no one else will accept him--just like how abuse happens irl. I've read Chinese raws of later chapters, and *spoiler alert* Kouichi hadn't helped Mitsuru's self-esteem at all in their 5 years together--now add that to the "no one else will love you except me" he's saying--Mitsuru naturally feels like he'll only have a secure (though not safe or happy) relationship with Kouichi.

Yeah. I think so too. Ofc, we don't want Shougo to be hurt but Mitsuru was hurting as well. Coming from a painful 5 years relationship, I dont think he can move on that easily. Maybe, coming with his ex in a hotel was not wise, but still he did not deserve to be treated like that. He was broken and confused. He was trying to start a new love and starting again after being hurt will be the hardest. It's not surprising if he will feel insecure and have trust issues. That is why, I would want them, Mitsuru and Shougo , to talk it out personally, so they can say their true feelings. Hopefully.

Kouichi didn't kidnapped or physically imprisoned Mitsuru. Well, I know he did send that video, but Mitsuru was the one who chose to follow him - to the hotel to put, and he was happy with the invitation. It's like you willingly go into an opened hungry lion's cage and you blame that you didn't know the lion would kill you and eat you... Moreover, you do know this lion has been behaving that way for 5 years. I mean, if you're an adult, you have to see what's coming.
What I mean by 'deserve' is that when you yourself choose to do something - oh, let's be honest, most of our choices are made by 'ourselves', unless we are having a loaded gun pointed at us or are hypnotized or are sleep-walking - you have to take responsibility for that choice - the consequences. That's all.
Well, I'm the kind of person who hate all kinds of cheating, so maybe I was a little harsh and didn't use the right words. Allow me to put it this way: Mitsuru was not the problem, his behaviour was. He, as a person, doesn't deserve to be treated badly. He, as a person, has to take responsibility for choosing to be treated badly.
And I think some people are misunderstanding when saying Mitsuru didn't choose to be treated like that. From what I've read, he saw that coming, and he did take responsibility - not a wise choice though.
I get why a lot of people are all like, "the uke's so dumb" or "he doesn't deserve Shougo," but Mitsuru's been in love with that scumbag for 5 years (or more), and that worthless piece of shit of a man has Mitsuru wrapped around his finger. Yeah, Mitsuru shouldn't have gone into the hotel with him, but it's hard to say "no" to someone you've been (and still are) so deeply attached to, especially when they've thoroughly manipulated you to be completely under their influence. Of course, Shougo doesn't deserve to be dragged into this mess, but just b/c Mitsuru is naive or even "stupid" doesn't mean he deserves what his ex did/does to him.
