Cover&Title: the cover is pretty beautiful with overlooking a vast world, it really coveys that this is an exploring adventure (the current one isn't my cup of tea but its alright). The title spoke as if its a tragedy about to unfold, it just feel like a bait for the wrong audience, and repeating the title twice in different language is pretty generic. (3/5)
Synopsis: introducing like any typical isekai story, nothing to complain about. You laid out the general plotline, introduced the MC's past life and the motivation to a certain extend. Still this has everything perfect for a drama but seeing the what to expect describing it as a relatively lighthearted story which leads to confusion. You are giving off two different vibes which isn't good, maybe you can make do without the "What to expect" section in the synopsis. (4/5)
Chapter: the pacing is slow to say the least, out of the chapters you have I don't get the sense of a story happening after three chapters, the fourth one is where I feel it really begin. I can see that you are trying to introduce the world while giving context to the MC's family, but I don't think its a good way since readers might easily get bored especially if they are a veteran reader. For the story itself, as I mentioned before, it feel slow, while there is clear progression in the timeline, it feel slow like any age progression story, whatever personality there is, except for the MC, feels barebone, you need more description to their expression, give them gestures to make them feel alive. For a story still in the explanation phase, I find it lacking in many ways but still good enough to read just for the world alone. And since you didn't met my criteria of 5 chapters, there will be no score.
Conclusion: you can cook but you need to work more on the characters, your world is interesting to say the least.
P.S, since nobody answer it for you, there is no worldbuilding tag because it isn't a tag, its a process.
