The male leads were trying to kill the MC for about 5 or 6 cycles, due to the obsessive love for the 'other' female lead
when suddenly, on the seventh cycle the male leads all drastically changed their attitudes toward the MC, the main female proragonist.

They expressed their love and passion towards the MC, with sudden reminiscence of beautiful memories of the MC,
(which is quite absurd if you think about how she was brutally killed six times in the previous cycles.)

I mean, male leads? What's your problem? What's with that drastic change of attitude? Why are they so suddenly obsessed with the MC?

As hyslee69 said, do not get mixed up between the previous cycles and this one. In her past 6 lives, she tried to go through the Love and Die ending of each of the brothers.

She couldn't quit as soon as she regressed because of her debt. After her debt got paid off, she was in quite a high position (being a chambermaid) and she was also the only one. She couldn't quit until another chambermaid - Louise - came along.

Also in this life, she said that one of the young masters saved her, and that led her to make a different action than what she has done in the previous lives - actually approach the young masters. She wanted to know who saved her. It was because of this difference that the male leads grew closer to her than in her previous lives. That is the main difference that les to a big change in Irene's 7'th life.

Why couldn't she just make an excuse that she wanted to travel the world? Let's be real - traveling costs. Money would run out quickly (money she didn't have) and both the male leads and Irenea knew that. Running away would be a form of betrayal as they are the GODDAMN MAFIA. They would have to let her go willingly if she wanted to leave. She would also get quite a bit of money once she quit, and she needed that money for her post-retirement life. She also didn't think that her retirement would be rejected. She's too used to the games' rules that Louise is the only one that matters and she's just an extra.

I'm not going lie, some of them are pretty well - founded. Honestly, I was rooting for Otis rather than Ahibalt but his 'betrayal' in the fourth life left me reeling.

On that note, I noticed some people complaining how the the expected Irenea to be some indifferent, cool person, but they didn't get what they wanted. I think there's been a misunderstanding. Irenea was never the type to 'not give a f*ck'. She was the type to give one. It's why she feels so guilty towards the other characters (especially Louise) for pushing them towards misery. It's why she legit has trauma over it. Also, its not that she has an indifferent attitude, it's just that she has demeaned herself so much that she just considers herself a tool rather than a person. Girl has been through so much shit, it's a wonder she didn't go mad.

Her depression and the thing with Otis left me heartbroken for her. I now understand why Otis wasn't the male lead. It's sad for him since he doesnt remember that life but it also explains why she would never end up with him because of the sheer hurt she felt and why she rejects him more than any of the other brothers as well.

Ahibalt is the best male lead for her. He loved Irenea in all their lives. I also read the spoiler thread for this and realised too that we never get Ahibalt actually saying anything romantic to Louise. Irene only saw the ending scene and she never heard his reply. As cruel as it is, could he have been using her as her replacement. That also explains his dark obsession. Although his mind didn't remember her, his heart always stayed honest and that's what makes him better than most male leads.

Rodion never really had male lead energy anyway tbh. I think he rather feels adoration and love for Irene as one might feel for a mother or elder sister. He's just dependent on her like that. He never really have any true signs that he was IN LOVE with her.

She's not fake, if that's what you're wondering. She's genuinely that pure and innocent. We do get scenes between her and Irene, although I admit it can't compare to the scenes with the male leads. I read some spoilers and found out that Louise plays a major role towards the end of the story. She apparently sacrifices her life for Irene? I don't know much, as I didn't want to spoil myself too much. Edith too - I didn't expect her to know that much. Anyway, Louise will DEFINITELY get more scenes towards the end.
