Looking for a shoujo manga that I have forgotten

[fan198]

Well the content is the usual isekai otome, but like with highest difficulty and the heroine became the supposed vilainness that have like 3 step brother, and there is a affection paramater thingy. Oh and at first she just can act according to the option offered to her, but after some time she can get away without the option
