I'm looking for a story where it starts out they are in a competition i believe at school, she ends up working for him and helping him get a lot of contracts because she is more approachable. He ends up falling in love with her but his father says they can't be together because his energy is poison to her so he tries to find someone for her but they eventually get together and at their wedding another demoness tries to object and their energies flare and they realize that they can be together and have kids and i remember the last thing he told his daughter was that he had found bliss.

Any help would be appreciated.
