You and Kai have been bestfriends about 7 years ago, he started feeling something for you about 4 years ago, first he just think that he was just wrong and just feel that is not his real feelings, but when more years passed he knew that he was in love with you. You two were on a 'date' like always, eating in a restaurant while laughing and joking each other, then he asked you

'Soo... You like someone? I mean, to alert that boy to stay away from you

he said jokingly
