The Seventh Day (Traditional Chinese: 最美麗的第七天) is a TVB modern romance series broadcast in February 2008.

This is Kevin Cheng and Niki Chow's third successive collaboration following 2004's Hard Fate, and 2006's Under the Canopy of Love.

Different people have different attitudes to love – even those born on the same day in the same year do not necessarily share the same views.

Yau Chi-Wing (Kevin Cheng) and Hui Wai-Yan or Don Dum (Bosco Wong) were both born on the seventh day of August, but one takes relationships seriously while the other is very materialistic and sees love as a tool to get higher up the social ladder.

The tale begins on the seventh of August, when Wing and Don first encounter their dream girl on the same island.

He gets to know pet shop assistant Ling Ka-Yan (Niki Chow) by chance and is soon mesmerized by her endearing personality.

Don, who works at a coffee shop, meets a romance comic artist called Wong Chi-Kwan or Sasa (Natalie Tong).

On the other hand, Sasa also pretended to go out with him so that she could get ideas about relationships for her romance comic.

Meanwhile, Sasa couldn't think of an ending to her comic so she needed to break up with Don to know what it was like.

Don finally found out that Sasa wasn't rich and that it was Jessie that was.

Wing had to go to Japan to look after Yuen Ching (Selena Li) since people thought she was dead.

Yan was sad when Wing had to leave so she decided to go to Japan a few days later to surprise him.

Don also quit his job and restarted a company with his friends, Dino, Martin and KK.

Wing finally found out that Yan left because of her father and decided to leave too.

To hide the fact that she has cancer, Yan said that she was angry that Wing spent so much time with Ching and that she now has feelings for Dr. Long.

A while later, Wing gets promoted to the senior position in his job as an interior designer, and the same day Yan visits his office and announces to everyone that she is pregnant.

Her family and Wing decided they couldn't wait any longer and Yan had to get a Caesarian operation to get the baby out and remove the tumor.

Don finally persuaded her, just before Sasa wants to give birth on the street.

With both Yan and Sasa about to give birth, Wing and Don coincidentally meet each other in the hospital.

After Yan gave birth and removed her tumor, Wing fulfilled a promise which was that when Yan gave birth to a healthy baby and removed her tumor they would all go as a family to a beautiful place in Japan.

The family continues the tradition faithfully, but after five and a half years, Yan dies from cancer.
