The problem with Jeongsu is that he’s nice to all the girls. He treats them all the same with his sweet and gentle nature, which causes confusion for the girls who are interested in him. He was also really sweet to Youjin during the double date, even though he sees her only as a friend. Sian is aware of this, and I doubt she will choose Jeongsu for her next trip to paradise.
