This yaoi doesn't make any sense... Just cringy

You seem to be the only one who's confused. You're cringy for thinking that speaking your opinion about a "YAOI" would actually be heard and agreed with. Sometimes it's best to not voices your thoughts until you know for sure that there would be someone who will agree with ya. Cause as you can plainly see it's only those who don't agree with you who are responding to your premature opinion

I didn't understand a thing... I can just see is the typical sick relationship

True. But for once it's mental problems we can read/research about (which is what I meant with 'actual problems'). Usually the problems are just 'being batshit crazy' or 'somehow fucked up in the head'. So I can appreciate this plotline more since it's about problems that aren't so far from reality.
And it's not all that unhealthy either considering we saw at the end that the characters just may end up developing feelings for one another. If not, it's still a somewhat minorly healthy co-dependence relationship. Not really the best or satisfying kind tho... And it may just turn to crap and they go their own ways, which may just be for the better. But that's up to the reader since we got an open ending that can go either way.
I guess the genre tag is just way too infested with the crazy, nonsensical and way too unhealthy or just disgusting plotlines nowadays. Makes me wish we had a seperate 'psycho' tag to throw those messed up stories into. (Because those are the stories I usually come across and they made me somewhat hate the genre to be honest.)

I don't understand this manga anymore...

The dream world was created by yellow dragon in a way to prevent the uke from dying again. To get out of the dream he had to realize everything there was fake, when he woke up yellow dragon again in the real world that became his reality. Everything is happening because yellow dragon apparently if im correct, turned back time in able to get the Uke.
Why is he and you guys so shocked by that dick? He already had it once and he was totally fine ahahah
Lol you’re right .. but as I recall.. he has not seen it in the earlier chapter.
