Alchemist FL, oblivious to her high-level skills.
ML falls hard first.
Very new, only 1 chapter, so this may get taken off if turns out to be terrible.
Two different people from different fields who are too good at their jobs, get abandoned. When crossing paths, they bond with each other over terrible work and agree to team up, starting what maybe a lovely friendship to relationship scenario.
FL has been abused and used by her family, as she didn't have the family magic (and had not been noticed to have a different variety of their magic which is even rare) and grows stronger while living with her fiance.
ML is traumatized from a young age, and in world of magic, he has used magic to forget his pain by getting rid of his emotions, but it now wearing out and he may have to use his future wife to take away his emotions away once more once she knows how to weld it.
Music is a religion and it can heal the countries they are in by making unity with the people. Through in some areas this has become twisted.
FL had been pretty much abandoned by her family from a young age emotionally, raised by the priest, she fell in love with music as it has made the worse days of her life bearable.
Beloved classic
Fl raised in the army (family had wanted to get rid of her and instead got some karma) and due to circumstances ends up as the emperor knight.
Ml falls first. However a very, very slow burn
Ml is obsessed with dragons and had basically forgone everything but his obsession.
When fl comes, she both teaches and helps restore order to the lands he owns.
Communication between the two helps alot (no consistently silly misunderstandings here)
