Iirc, he loved her too much that he wanted her all to himself. I think he kinda got manipulated by yvonne(?)

he is a yandere so he goes crazy

I've readed this on someone and they said that he would be like controled by yvonne's magic ig??

By magic it was the younger bro. Eclis did everything on his own.

ooff i see. Thank god, i though he betrayed her for Yvonne
