The storyline is very common but it adds it's own twist. I just find it confusing as to when the "yandere" part will kick in seeing as 2 of the characters dont seem like they are going anywhere near that demographic. But that Oswell seems to be one, tho I think his affections are directed towards Cecil rather than Layla :/ I think that's the direction that this story is taking. They are trying to make Cecil the centre of everyone's affection and the otome game, creating her a reverse harem lol
The Result of Being Reincarnated is Having a Master-Servant Relationship with the Yandere Love Interest
