These dramas are very different from one another. Country of origin, overall plot, length, feel, etc...all different. But I couldn't help but think of Oh My Ghost when watching Toki wo Kakeru Shoujo.

Both dramas have a character that's stuck in present day when they're not supposed to be there, whether it's because they died and haven't passed into the afterlife yet or because they're from the future.

I won't go into more detail than that, as it gets too spoiler-y, but I definitely saw parallels between Shohei and Shin Sun Ae.

Even though the settings are different, I found many similarities between the two dramas:

- A cold, selfish but brilliant man becomes in charge of a group of people
- A sweet, warm-hearted girl falls in love with him
- A kinder second lead pines after the girl
- The dramas concentrate on the lives of the group of people also rather than just the main couple (more so in Beethoven's Virus, I think).
- Main lead makes decisions for the group that others don't approve of, causes drama
- Main lead slowly earns the trust of the members creating a more united team

The only major difference I saw was that there wasn't as much of an emphasis on romance in Beethoven's Virus as there was in Pasta.
