The Yandere Magician Can Only Love The Statue Maiden
Ongoing | Crane,クレイン | 2019 released
Actually a pretty compelling plot and provides solid reasoning for ML yandere tendencies. It is a bit annoying in the beginning when the plot flicks back and forth between the flashback and present but is necessary to draw maximum angst in reader. Towards the end the relationship does start feeling very rather than cute like in the beginning as the FL passive nature causes her to be completely taken advantage of and easily manipulated by the ML.
