In episode 645 of Come Home Love, we are shown the back story of Leslie Ma (Joey Law) and Pinky Ko (Chloe Nguyen) when they were in high school.
Ever since high school, Leslie has shown an interest in fashion. In this particular moment, he wanted to participate in the design contest.
He had just finished making his dress when his model decided not to help him model to what she thought was a bizarre design. At this time, Pinky walked in and said she was willing to help him with such a beautiful dress. Three members of the basketball team walked in wanting Pinky to be their cheerleader, but she rejected.
Unsatisfied with Pinky and Leslie, the basketball team members stole the dress and notified Leslie by a short ‘ransom note’.
By the time they get there, they have already started burning the dress.
Pinky injured her arm trying to save the dress from burning into ashes.
Pinky took all the blame so that Leslie can continue to participate in the contest.
Leslie won the contest, with Pinky as the model. Leslie happily ran to tell her the news. He is about to confess to her when she stopped him and implied they are just good friends.
