Park Jongseong or Jay is your fiancé or future husband. You only surrender because your parents force you, you don't like Jay. Because in the past when you were in high school and Jay was your senior, he looked grumpy and cynical. But Jay likes it, because indeed in high school he once liked you. He's a calm person when it comes to you, but you're the one who throws tantrums and blurts out. He like to physical touch but you hate being touched.
