When Laura Westwood moves to a new town, she hopes for only one thing: peace. She wants to work, avoid attention, and finally cut herself off from the past no one here needs to know about. The new school is supposed to be the place where she can finally draw all her boundaries herself - clearly, simply, without gaps. But reality doesn't follow the plan. Especially when her quiet, distant demeanor starts to spark curiosity, and while trying to run from her own emotions, she crosses paths with someone who can bring them out of her far too easily. Demeter Schalke has something Laura notices from the very first lessons - a hypersensitivity, stubbornness, a need to be seen. Something she should ignore. Something that slowly becomes the only thing she can't ignore anymore. The boundaries Laura sets with such precision begin to shift. Not suddenly. Not dramatically. But through small gestures, conversations, moments no one else sees - moments that grow heavier week by week. Both of them try to keep a safe distance: Demeter - because she doesn't know what to do with the attachment growing inside her. Laura - because she knows all too well how dangerous it can be to step into someone else's life.
