The lack of empathy, the preoccupation with power, his manipulation, his grandiose self perception ( he is the human among ants as he puts it), the way he gets easily bored, the way he feeds off excitement and chaos and even the fact that he can't remember names and faces well are all common symptoms of Narcissistic Personality Disorder.
Having encountered a real diagnosable narcissist....the ML is eerily familiar ( minus the blood shed ofcourse (⊙…⊙ ) ).

All three are incredibly unlikeable. I feel like that's the point though- that they are severely flawed but still maneuvering love just like all of us.

Ofcourse not Viira . Obviously the point of my comment is not to insinuate that anyone outside of the story is a rapists or to justify the actions of the character. I'm saying the point of the narrative is that they are awful people. Awful people exist. Awful people maneuver life- some are redeemed and some stay as reprehensible as can be imagined. If the author wanted to create a story with perfect people we wouldn't all be in a twist over it right now would we ┑( ̄Д  ̄)┍

Otherwise I very much enjoy stories about messy and morally ambiguous/shitty people. If you’re into that maybe try this one if you haven’t yet, Happy of the End. It is a little heavy with some of the genres prevalent tropes about abuse but a lot of people that have done or do shitty things trying their best with each other

I like it. The uke is inherently flawed ofcourse.... but those are my favourite. I love strong, capable, confident bottoms. Rather than cowering to each other's whims, I want to see them face off The more ruthless and morally questionable he is now, at least I have a little hope that his redemption will be all the more impactful. Isn't that the point anyway... to give us this ML who does reprehensible things and somehow realizes the error of his ways after much character development?
The art is nice. The plot is fine with me. I'm in. Yaoi is full of sexual assault. It's our own duty to regulate what we choose to read. I've stopped reading content where the assault is gratuitous before, and I don't mind when it is used as a plot device to set up the story. It's important to be able to separate our hate for the actual act of assault from our feelings towards works of fiction that may have no connection to our own underlying thoughts, opinions and experiences.

I really like this manga and look forward to seeing updates. I'm not mad at Masami for having multiple partners at all. It's something he's honest about but not necessarily proud of. I get that people might be upset at this lack of good moral judgement but.... that doesn't take away from the fact that otherwise Masami is a caring, generous sweetheart.
There are many things that could've caused Masami to begin indiscriminately cheating. I feel like most of his other romantic relationships are in the pursuit of sexual gratification and praise. Even when he finally realises that Tora is all he needs, he's only hesitant to change their relationship out of fear of the unknown...of being discarded. He's afraid of being alone and I think multiple lovers are just a safety net. Can't wait for more development!

You wouldn't be feeling that way if you devoted your time, love and welfare with someone only to find out they were cheating and have sexual relations with 4-5 other people behind your back.
It's all about perspective, hun, and tbh as a trauma survivor on multiple fronts someone like Masami being in a relationship with someone like Tora just reeks of toxic co-dependency and is not healthy in the least.
Do they love each other? Yes. Probably more so than we think. Is it healthy? No. So far we know that Tora is a trauma survivor and has never sought out actual help for it. He literally thought Masami was someone sort of pure angel till he found out that-- surprise, surprise!-- Masami was actually garbage. But! He chose to cling onto Masami 'cause he was the first human to ever show affection towards him.
It's the same thing with Masami. We don't know what sort of trauma he is hiding but it's obvious that he hasn't sought help if he's turned to habitual cheating. It shows that he is unhappy, unsatisfied or scared of something happening to his well being so he puts himself first before others and seeks out whatever pleasure he wants regardless of the risks (we see this play out with the abusive psycho. There was literally no benefit to that relationship other than the sexual gratification he got from sleeping with his boss.)
It's not cute, brave or understanding that Tora put Masami's needs before his own. It was self-sabotage or martyrdom if you want to romanticize it for whatever reason. Masami may have some sort of past but as far as I'm concerned he's got a LOT of growing up to do before at least myself to see him as a proper partner for ANYONE.
