The first world is the most problematic one due to consent issues. I don't like when characters says they dont want a relationship but are force and it turns out that they were just in denial. This type of premise is very problematic for me. But in this case, the overall conclusion made up for it since the ML's soul is the same throughout all the worlds and he learns his lesson of not forcing the MC to do anything.

I liked how they tied up the real world with the worlds that the MC visited. They sort of served as an experience for the MC to realize that the ML was in love with him and open himself up to the opportunity to love him back. The way the ML falls for the MC doesn't really have a reason. He just feels that he is special and he likes his mannerisms, so for those that don't like the insta love that could be a problem. Now MC takes a long time to fall for ML and to accept that he likes being with a guy. ML has been very devoted to MC for years, but MC is completely clueless and only sees him as a friend.

I have to say this novel had the best system that I have read so far. I really want this type of system. Just go off into all these fictional worlds and have adventures and then come back to your regular life. Sign me up please.

In first arc, ML rapes MC since MC only treats ML as younger brother, it is bittersweet in the ending though. When the MC is about to leave the ML is free to go anywhere, and won't force him as long as MC doesn't leave him.

Second arc, the MC loves ML so it's kind of morally okay LOL.

Third arc, the ML hypnotizes MC and do the deed and when it is done the MC doesn't realize it. So kinda worse than first arc for me

The ML is MC's handsome roommate in real life like it's sweet but WTF?

First world is historical setting and ML is a litlle bit yandere, so here are tragic monents. Second one is fairy tale - mostly positive. And the third one is cultivation world which I like the most because of unpredictable setting with time travel and death and than another transmigration to the same world into the body of his

Using this damned sort of thing as a plot device? It's getting real old... I mean, yanderes are fun and all, but imagine a man going about, who has no qualms about raping you and shoving his d*ck inside without permission, just because 'he loves you'.

the ML gets the MC drunk and then rapes him. Unlike many series where rape, which is nothing but an act of violence and disrespect, turns into love, the MC does not love his rapist. Instead, he very reasonably rejects the ML's feelings and escapes. Unfortunately, he is captured by the ML at the end of that arc and is forced into being his s*x slave. The ML is manipulative and emotionally abusive, preventing the MC from leaving their chamber and refusing to give him any clothes. When the female love interest arrives, the ML forces the MC to sit on his lap, and the MC lies and says they are in a mutual relationship because he's scared of being raped again later. Surprise... The ML rapes him afterward anyway. The ML, the person who was originally the hero, has completely become a villain by the end. It's a very tragic Bad Ending, and the MC has also started showing signs of Stockholm syndrome. He is tortured every day until he finally leaves that world.

The MC becomes a cat. He eventually gains a human form but can freely return to being a cat. This may be able to use to escape the ML or avoid him if he turns out to be as emotionally and sexually abusive as the ML from the first arc.

It actually starts out fairly sweet and the MC and the ML have a good relationship, In the beginning the ML was very much aware of the fact that he should not treat the protagonist like a possession, sadly the circumstances they experience push the poor guy and he goes a bit strange in the head.

The MC is not blameless for that breakdown in the relationship, because I think the two of them talking it out would have helped, however he is not to blame for getting raped and he is very much appalled and angry at it - rightfully so. The ML also knows what he did is wrong, he has his reasons, but they don't make it better. I sometimes feel that there are elements of Stockholm syndrome, but its not quite the case, since for all that the MC cares for the ML, he still sticks with the facts - what happened to him was wrong, but before everything else the two guys were friends and he cares about his friend and does not want him to be unhappy, which is part of the reasons I think this story is great despite its flaws.

if the way it deals with non-con stays the same. Namely that the characters know that it is wrong

Im not gonna sit here and pretend I'm a saint, I usually don't care that much about the r*pe trope in bl I've gotten used to it which really isn't a good sign but the ML repeatedly raped the MC he knew it was wrong but did he stop? No. And the MC eventually developed some sort of Stockholm syndrome because the ML basically kidnapped him and wouldn't allow him to leave taking away his clothes so the MC couldn't leave, and again just kept raping the MC, I honestly just hated it.

He gets raped repeatedly by ML and even in the beginning he gets molested multiple times while sleeping. The ML is yandere for no reason (he's a small boy for one chapter and then the novel time skips quickly so that he's bigger already). It is revealed very early on that the ML was his roommate in college (although it was just a passing sentence that can easily be missed).
