it's a romance historical webtoon where fl and ml are in a loveless arranged marriage and fl has a lover who was a knight. One day when a war broke out, the ml sent fl's lover to the front lines where he died and fl grieved which the ml found satisfying (they lowkey hated each other) and fl swore to him that she'll make him experience the
pain she felt by killing the person he'll fall in love with in the future.
omg they got the "cherry blossoms after winter" treatment
and by that, i mean it going from shounen ai to having smut scenes
