I need to find this manga

[mortuz]

There was this specific isekai manga where MC is sent to a kingdom to resoleve the political and economical problems. Impressed by his work, the king decided to make him his successor. In the next chapter the King's daughter finds about the events and tries to confront the MC. Surprised by his efficiency, the princess felt disappointed in herself for not knowing any time sooner.
Does it sound familiar to you?
