yes she will. She sleeps with all of the ML's with the exception of God bc he was only there for like short duration and then disappeared without any mention. She's already slept with Nadricka. After that she will sleep with Robia, and then with Sieger/Seeger, and then with Ecklot, and then with Karios. She also sleeps with Ettsen but that wasn't until the 7th volume of the novel (aka the end). Technically she already slept with Ettsen in the first chapter but we didn't really see that bc it was more of an implied thing (it was explicitly said so it's not implied but you get my point).

this is the only translation i could find of it but it only has 4 chapters of volume 1. the last update was 2 days ago so there could be more in the future.

[ENDGAME SPOILER]
it is a reverse harem ending so she won't pick one guy. She becomes the emperor. Feel free to ask me any questions regarding spoilers. For those that don't know there are 7 male lead's (although 1 isn't including in the ending).
- Nadricka
- Eckolt (loyal black haired guy...also a virgin)
- Robia (librarian guy with blonde hair)
- Kairos (he's the purple haired guy we saw that she was supposed to meet with. crown prince from another empire)
- God (we meet him after she dies but he disappears after she goes back to the time period she was in)
- Seeger (the knight guy that's tan and super ripped lol)
- Ettsen (red headed bitch...sorry i can't forgive that bastard for the way he treated our fl)
^^ those are the male leads (if u don't know who nadricka is...reread the story im sorry lmao)
