Mc is not a very instantly falling in love kind of person, he simply decided to go get himself a wife that fit his desires of smart, talented, very loving, taller than him and he decided to do it in a very simple way, he had his servant go check the student registry for different female students that are commoners or even surfs and got into the magic or other regular university's through scholarships or recommendations then he decided if they look decent and went and tested their personalities personally by talking to them before he introduced himself and getting to know them, after deciding on which girl he thought was perfect grade wise and personality wise he would talk to their parents about an arranged marriage where they would join him in his personal Nobel manor and live with him and be taken care of as long as they gave him permission for their daughter, that was his plan. Instead mc finds out about two twin 3rd year mages, at one of the magic towers universities for the study of magic, who have decent grades and are above average but not that special in any of their classes but they fit what he wants in marriage well they are both sweet, one is more submissive while the other is kinda dominate, they are both tall, they have commoner background, and to him they are at least talented enough to become 2nd circle magicians at 22( MCs new bodies age is 16) (also second stage is pretty basic but most soldiers in most countries military in this world will reach the 2nd aura stage or 2nd magic circle before 30 so they are only above average. Mc convinces the parents then takes them over to his manor that his father gave him to explain to them that they will be marring him
