Her dad is a noble that they thought was a knight, the teacher has a one sided love obsession towards her bio dad, that makes her kill leo's mom in exchange of them be together in the future but the dad didn't show up and just went away. The dang connie instigated everyone in the orphanage to abuse leo and make it look like she is leo's savior so when she met leo's dad she can put a good word about her and apparently in og leo died too.
Well damn ╥﹏╥
whaaaaaaaaaaaaaaaat ?
Oof! After reading up to check 112 I couldn't help thinking the teacher and leonie's mom's knight were a team. My theory was he deceived both women even though I couldn't see a motive. But child trafficking....yikes.
