It's a Shoujo in a village where one can live again with a ritual, but they can only live within the village alone if they leave the village then it is the end of their life (for the revived). I remember, there was a woman who did not know that she had been revived and was curious about the things outside the village. She tried to get out of the village and when one of her hands crossed the village line, the woman's hand disappeared

Any recommendations of where they transferred from Isekai to modern world? It's seems cool.

I'm not sure if this meets your needs, and it's a BL, but

seems to kind of meet what you're talking about

I had read a yaoi manga where the uke always sunbathing on his garden butt naked, and the seme accidentally watched him in his balcony
Can you tell me what it is called?

Is it Shousetsuka no Shitsukekata? I think it’s chapter 4 that you are talking about. Hope it helped :)

Is there any manga with Hanahaki disease? ヾ(❀╹◡╹)ノ~

Oh wait, there was actually a webtoon that was based on hanahaki disease called "Spring in the Heart" by Bbong (also the creator of Never Understand). It was the winner of a contest in Lezhin, however, it was disqualified because the Hanahaki disease concept is actually patented.
So a manga with that concept is probably not feasible because of copyrights stuff. ╥﹏╥

It's honestly bothering me if the author of some manga seems to be more focused to the other couple in detail rather than the main couple.
For example : when the other couple already have sex but the main couple only got a kiss scene.
It's only my opinion, what about you?
[Don't hate me for this (/TДT)/ ]

Do you know this manga?
It's a shoujo, the girl's able to fly, she live with her father, she's searching for someone while flying in the night sky. And there's this boy, he know the girl secret. And one day there's an agency trying to catch her to examine her power. After a while I dunno where this girl and her father go and leaving the boy alone, they do that for the girl's safety (I think?) but after three years she go back and meet the boy again
Sorry for my bad English ╥﹏╥
Not only the cover but the chapter images also won't load properly
