Straight Male Harem Magnet, No Falling in Love at the Start. Let Me Feel the Protagonist’s Charm

Looking for books similar to *Immersed in the Villain’s Harem of Admirers*. Are there any straight male heartthrobs with a crowd of admirers? I want sound logic, and no falling in love at first sight. Does being a heartthrob just mean you’re good-looking? I want to feel that he has inner qualities and substance too!
