TVB drama, Line Walker (使徒行者) achieved the highest rating record in 2014 and many audiences miss the on-screen couple, Charmaine Sheh (佘詩曼) and Raymond Lam (林峯). In fact, both collaborated in Yummy Yummy, Lethal Weapons Of Love And Passion (覆雨翻雲), The Drive of Life (歲月風雲) and My Sister of Colourful World (花花世界花家姐) series.
