No, no they don't.

As it turns out, he kept his abilities when he regressed so he stars off the Apocalypse with a much higher rank than every other ability user. He also uses his regression to go gather supplies that would help him take care of his sister (from food to hygiene products) before he begins to train her how to fight when zombies first appears.

LL's sort-of-boyfriend from the previous timeline also regressed. At first he intended to pursue her but then he quickly realized that she is not the same as the original timeline. She had not spent years near him and had no attachment to him this time around so there was no development of feelings.

Being a sane guy, he finally realized that LD's earlier regression (as LD had at least a year earlier for his regression) had changed things enough that there was no chance for him to be involved with LL. So he gave up and let go of trying to chase her which is quite possibly the smartest decision I've seen a 2nd ML make.

his abilities mutated cause of rebirth.

Like f*ck, his psychic ability alone that could kill long distance undetected by lower tiers (which basically means everyone to him) is OP enough. What more his space ability that literally has a lifetime supply of everything from hot n cold water, bathtub, even freshly cooked food like rice or even oden that he apparently collected 1 month before apocalypse. Come to think of it, it was vaguely hinted that he may have confused the mind of those people he bought supplies from so they wouldn’t question him.

• He freakin pushed MC to the zombies right on day one “so she could adapt faster” like they were so pressed on time. Not even precautions like “they’re slow but be careful not to get even a scratch”. It’s MC’s first fr*cking zombie battle on day f*cking one! It’s really a miracle she made it out unscathed. Come to think of it they’re all still showing skin despite fighting close combat and on risk of being infected from a mere scratch🧐. But then again with ML this OP what more can I expect.

• He’s technically forcing himself on MC. Bluntly he’s a f*cking creep. But MC’s so lenient to him she can forgive him for anything “cause he’s the only relative she has left”.

• I like that he doesn’t restrain MC from socialising but body contact is a big no-no for him even from a close friend and kids. But again, MC’s so lenient on him.

• 3rd thing I hate about him next to being too OP and a creep, he never tells others of anything. Sure he’s cold, not much of a talker, and he’s fr*cking OP. But serious matters need to be told such as “Guys, the research institute has their eyes on us because of me. They can do very underhanded things so keep an eye open.”

example of how meticulous ML takes care of FL is that he even made sure to bring skincare in his space for her... And while she eats he trims away her hair split ends for her. So when reviewers said he's mean for throwing her out to kill zombies so soon, I disagree because all were within boundaries of his control.

One thing that's super anti climatic was when they finally did the deed. After all that teasing the author just kind of breezes through the scene.

The ML comes back in the past to 1 month prior to the Zombie Apocalypse. During this 1 month he supposedly travels the world and stocks up on supplies, food, weapons, resources, and everything you can think for an apocalypse. This is a logical approach for someone who knows the future. However, what's unbelievable is where is he storing all this stuff? Not to mention, is he stealing such stuff or buying it? Where did he get all the money to buy and how? For example, grenades and guns.

If the ML came back prior to the apocalypse, no one should have powers yet. In the future, he would have space powers, but at this point in time he shouldn't. And even if he did, wouldn't he start off at Level 0? Instead he can store cars, RV's, and anything in the sun in his space. It's just illogical.

There's a small mention that he's mutated since his Rebirth, but this is still illogical. How can he physically retain his powers from the future? This aspect of his powers bothered me quite a bit throughout the story because he's an OP character with not only his future knowledge, but with his OP powers as well.

As for the romance, it feels very off kilter. In the past life, the ML was not the love interest of the FL. After getting revenge on everyone directly or indirectly involved in the FL's death. The thoroughly blackened ML gave up and died himself, only to be rebirthed as former blackened character.

The result is that he's blackened obsessive ML that can't bear to have the FL out of his sight. Although, the ML & FL are step siblings with no blood relationship, it still makes an uncomfortable reading in the first half of the story because the FL obviously does not have any romantic feelings for him.

It's a given that the FL would eventually fall for him because the ML really does focus on the FL being happy and being herself. Despite that, it still doesn't feel like a normal romance. It almost feels like obligatory or a patronizing type of love.

The FL is a carefree type of personality. The type that doesn't sweat the small stuff. As long as it doesn't go badly for her, she'll just ignore all the negativity. So while she knows the ML is a ticking time bomb, she ignores certain signals and caters to his obsession.

So while I liked the ML & FL characters, the story wasn't very exciting. The ML's OP character did not provide any suspense in the story. Even the romance felt a bit flat, because even though the ML has an obsessive love. The FL struggles w/ their step sibling emotion & only gradually gives into the ML.
