When Harry Styles said, "My favorite thing about the movie is that, you know, it feels like a movie." I totally get him cause that's how I feel about this manga. I went in expecting the usual isekai nonsense, but catching me off guard, this is an actual story with an actual plot and actual likeable, developing characters.
I love everyone, and the story was touching. I think it could reasonably end with an open type ending with ch. 21. But nevertheless, I look forward to more adventures and seeing what other worlds he's traveled and heroes he's met. Plus, I genuinely like seeing him and Tia together.
Good story, look forward to more.

I read somewhere that apparently in the novel all of his family ultimately dies and Tess later on too. Is this true? I need to know so I can prepare my heart for that.
I want to believe the person that left that post was just playing but if not... (T_T)

Most people die yes, the mother and sister live, the king and queen of the human and elf kingdom die, and most of the mercenary group except for like 1 or 2 .Tess is neither dead or alive she has some one else inhibiting her body. However this may change later I haven't been up to date with the novel.

Sure thing I use this website, it's free haven't had to pay or anything when I used it. It's been awhile so I'm not sure if there are any changes.

No, I'm here too early. This is not a story to be read in parts. I need 50chapters I can binge at once. This is so good. From the very first panel I could tell it was going to be something really special.
Mori, Rider, Aia, the god-like aliens, the quality art, the growing mystery. Everything is *chefs kiss*
Yeah, I can't read this. MC is brainless, and the plot is brainless. The premise starts off interesting with character possession, but wih the twist that her first attempt fails. After choosing death and cursing the true villainess, she finds herself with the choice to load like in a game. Par for course, she chooses to try again. That's where things begin to quickly fall apart. The first point could be due to translation issues, but she states that the load point must be from when she possessed the character. However, that's quickly disproven as she then follows the contradicting train of thought that she had already broken off from the villainess and chased the OG!FL's route. Ok.
Following that, the second interesting factor: the item shop is opened. However, we the audience are given no preview for it, and therefore, no hype is created for how it could possibly be used to spice up the story. It seems it will be a boring deus ex machina like tool. Likely, wherever a plot armor event happens that can't be explained, the MC will probably just say something like, "Sure am glad I bought this "item" from the store beforehand." Whatever.
In verse, MC glosses over it as well as she is suddenly ushered into her schedule for the day. More factors are revealed such as what the previous error message was intended for: MC inevitablely has holes in her memory. She can't even remember what her body's father's face looked like. Ok. In a later scene, it is proven that she can't even remember the layout of the mansion she lived in. Ok.
Then, what was the point of the regression? Regression is interesting only when a character can use it to change their life for better or for the worst. They don't have to be hyperintelligent, but at the very least, the character has to be able to make changes to the plot so we can enjoy the flap of a butterfly's wings events that follow.
All the MC has done is prove herself stupid and get blackmailed by one of the MLs (someone who can apparently go in and out of a noble woman's home whenever he wants? What are the servants and guards doing? Her father doesn't even question the breach in security. And ML, doesn't he have a job? Dumbass has to much free time apparently that he can just whimsically go in person to harass someone he apparently disdains to the point of death.). She's made no substantial future plans and is just letting herself be dragged around by everyone around her.
Oh, but not to worry. She most certainly did the most important thing a female MC should do! She made herself "prettier." Yay. Good job I guess.
Anyway, I persisted in reading until the scene where she accidentally gives the OG!FL alcohol. At that point, I just stopped. Made me too annoyed. She doesn't have to be smart, but at least give her enough of a brain that she's not that careless.
The story could get better from here, I don't know, but I don't have any plans on reading more.
