Both dramas have a actress FL falling in love with a ML that are in very serious fields(FMIYM: News Achnor, TYH: Lawyer).
Both FL's have an upcoming role with a job that corresponds to the ML's profession and seek out his help to do her best.
Both ML's are harsh towards the FL at first because of her life as a celebrity, but soon respect her due to the jobs hardships
Both FL's maintain a positive and cheery attitude towards their less-than-favorable circumstances

The main difference between these two is that FMIYM has a fantasy element to it while TYH is more so your everyday office romance.

Both are courtroom dramas. Romantic relationship between the main leads who are both lawyers. Hyena has more comedic elements and cases while Lawless attorney also has comedy but is more serious and more complicated villain but both keeps you on the edge of your sit. Also, if you're searching for a strong female character then say no more and click on lawless attorney.

There's not much similarity but I got reminded of Fall in Love with Me when I was watching The Brightest Star in the Sky. Many songs of the soundtrack is also sung by the male lead which are pretty good.
- Both of the male leads are rich with the female leads struggling with money (sorta)

- There isn't any time travel in Kahogo no Kahoko but the death premonition part is similar
- Leads in both the drama are an artist and a hard-working person
- focus on family
- A raw Japanese feel
- The female lead has a difficult father relationship

Both have a lot of the same concepts dealing with a big business run by a powerful family. This of course entails love, soul searching, fight for power, family drama, etc. and don’t forget - twists and turns throughout the series!

1) Both were extremely tragic , the sweet parts of the drama was simply there to make the tragic parts even more tragic.
2) Both male leads had concubines/harems
3) Both male leads do everything in order to become Emperor
Differences:
No-one can beat Li Cheng Yin (male lead) in Goodbye My Princess in how cruelly he treats the female lead and the trauma and torture Xiao Feng (female lead) is put through because of him.

1) Both male leads are hated/feared by their father as they feel threatened by them
2) The female lead gets close to the male lead for revenge for part of the drama but also deeply in love with him.

4) Both about palace intrigue
5) Both male leads have a harem
6) Both are tragic

Note (chocolate has a more serious vibe)

To be honest I got confused with the title with these series. Both have the same dark theme and body switching trope, but they have different storyline.

Both show tell a story of a husband with 2 wives. HBM is a story about the husband lost the first wife in accident and he married a second wife. However the first wife is back alive and meet the husband again. FW is a different plot where the husband married a wife but not happy with the marriage and was given a chance to change his lives in another world where he married a rich woman as his wife. However his previous wife in another live come back as his coworker in his current lives.

Both series give the same vibe about the love of family.
Female lead in both series loved their mothers so much and they both have a child that they love.in GBC the female lead go back to the youth time and able to see her mother that already pass away while in HBM the female lead is back from death and able to spend time with her living mother again.

They both have main couple who couldn't stand each other when they were in school together. They meet years later again and start seeing each other in a new light.
