POSSIBLE SPOILER!!!Originally Posted by kidd
Ma Siu Fu had a semi-relationship with Seung Ngor and not Mo Yau.
I love Fong Tin Yau in Part 3. He understood his feelings for Ma Siu Ling in Episode 3 and thus not as "Toh Lei Tai Sui" in Episode 3. In Episode 1, he went with Wong Zhen Zhen because everyone asked him to do so. He is never clear on what he feels for Siu Ling until they ended up in Japan together and when he fell into the "Ching Kai" (love trap), his deepest wish is to spend his life with Siu Ling as a "normal couple". Even then, he still continue with Zhen Zhen because it is the right thing to do and only told Siu Ling he loved her right at the end, just before she dies.
Siu Ling : If I die, would you turn me into a vampire?
Tin Yau : No, I would never do that?
Siu Ling : Why?
Tin Yau : Because I love you, I would not turn someone I love into a vampire and suffer like I do. Teach me what to do, I do not want to turn you into a vampire but I also do not want you to die.
In MDWAV 2, he is slightly better but only slightly. He only knew he does not love Zhen Zhen just before Zhen Zhen dies because Zhen Zhen said "If you do not love me, then don't bite me". He finally realised that he does not love Zhen Zhen and thus in the end did not bite her. However, he only knew he loves Siu Ling when Siu Ling is about to die from Nine Tail Fox attack and he told her "Zhen Zhen said not to bite her if I don't love her, I have decided to bite you instead".
However, even then, he did not tell Siu Ling outright he loves her until the last episode when she appeared to have die.
In MDWAV 3, Siu Ling and him are always confident of each other's love. They know they love each other, there is no second guessing. In addition, they is also the knowledge that they have a daughter and that further strengten their love.
