All I want is to become the perfect villainess, but everyone's intense feelings keep piling up around me!? An isekai reincarnation × doting romance featuring a young lady who knows nothing about love.

“I want to fall in love with my destined soulmate in my next life.” Those were Rena’s final thoughts before she lost her life in an accident.

But the “Villainess Plan” she carefully devises soon spirals out of control, as her sincere, single-minded, and hopelessly innocent nature draws everyone around her into the chaos...!?
