Anyone got any clue?

Mc is blond and i think the friend or sister that he escaped the slums place i think(i forgot, but she is like red head?) I remember a little part where his sister or friend(i dunno) was at a church cuz she had no other place to go so she was training priestess? but they were bullying her and so the mc came to the church and came for her essentially. And she cried and they hugged? I let it marinate to long and forgot the name
