??? Yoo Yong Min - ?? ? Learning to Live OST is sung by the barrister in the cafe that Park min young BFF owns! .... he has a great and very underrated actor

If you loved Kimura Fumino's role in this drama
You should watch Ito Kun, It's her best work in my opinion.
Watch the drama first, then the movie ( Ito Kun)

both movies portrays the touching relationship between guardian and child
Both child are saved y the leads when facing harsh life conditions and the leads that themselves lives a pitiful life finds healing with them

This series is one of the few cdramas I have loved a lot as especially its fantasy genre my favourite even though I don't usually watch dramas this long. It had similar settings as AOS different fantasy kingdoms, power levels, supernatural nd also the protagonist was also kept hidden for a long time similar as jang UK he had tragic events happened to him too since he was a child similar to jang UK

similar vibe
innocent female lead
bad/evil male lead (demon/comes from hell)
FL forced into marriage
male chases female first

In both dramas, one or both of the leads time travel within a limited period of time, trying to change events in the present/near future that they don't have the full picture of. The ML's personality changes from what it is initially (from cheerful to withdrawn/somber in MDD and from selfish to self-sacrificing in TWY), and both FLs are sunshine personalities who bring light to the ML's life. Both couples have very good chemistry.

Both have uncles that love their nephew's girlfriend
Both have MLs that secretly help the FLs
Both have uncles that are considered as head of the family

Maid's revenge is darker in tone while Don't mess is very lighthearted.

Serial killers and more serial killers. Both dramas deal heavily with serial killers and the police attempting to catch them. The pacing is tighter in Aku no Hado, but Yuki Furukawa and Nattarat Nopparatayapon are equally proficient at playing super creepy dudes.

Both male leads have lost the women they love to violence and are on a bit of a revenge kick. Seigi no Tenbin is milder in content than Voice, and it does have a tighter script.

Both shows have in common:
The female lead personality is alike.
Both female leads are called "Tiger Moth" because they can't help seeking for justice when in front of injustice even when the situation is unfavorable for them.
The MLs personalities are not the same, but in both shows, the male leads think the FLs should maintain a low profile, but they can't help caring for them and helping in the end.
Workplace romance. In Law Cafe the leads are lawyer/prosecutor while in Into the Ring they are public servants.
I like the cute male leads who support female leads!!!

Bad Guys is about gangster and mafia characters, and Kei x Yaku has a Yakuza protagonist. Both are damn good; I'm actually a little obsessed with Kei x Yaku not gonna lie!
