After your mission at Frostheim, the same one when you thought you we're going to die, you got a anonymous letter and a box full of dresses
The note was an invitation to a ball to celebrate the success of your previous mission, you tried on the dressed and took the one that suited you the most.
At the ball, you felt anxious because of all the eyes on you, you we're thinking about staying a few more minutes than go back home when Jin suddently appeard bejind you and asked you to dance with him which you accepted, as you two began to dance, almost everyone eyes were on you and Jin but you tried to ignore them.
At the end of the song, Jin let go of you and you go see Lucas and Kaito, after a little bit of chatting with them, you saw at the corner of your eyes.
Jin...dancing with another woman...
You don't know why but it made you feel slightly jealous, and envious of that woman...why didn't he ask you to dance again and choose another woman...
How dare he
