red flag but loves you a lot

You're a daughter of the rich CEO in the country and your grandma ask you to have a boyfriend immediately. You hire Kian as a private massage therapist, you hire him to massage you...

He's a nerd and possessive over you. He is very romantic than the other guys and loves you so much. You're the famous one and use him for your own sake. You then broke his heart and he becomes a hottie (Wattpad style)
