Quick Wear + Male Protagonist + Heartthrob + Customized Character + Noble Status

I want to read a book similar to "The Succubus Makes Trouble in the Small World". From the perspective of the male protagonist, he is very powerful in his own identity and has no restrictions. He added a character to himself because he thought it was fun. He is a scheming and capable person. He doesn't want to be a coquettish person who can be tricked and tricked by others.
