Since she can use healing magic anyway, it seems that she can simply receive requests from the local church and the adventurer’s guild for medical treatment. In the end there won’t be any real changes, huh?
Until her marriage she will perform the healing as apprentice nun of the church. After the marriage she will perform healing upon request, whereas a part of the reward will be donated to the church.
Apparently there are quite a few married women possessing healing ability operating like this.
