This is a bit hard to put into words for a google search but I am trying to find shows thats story/setting is mainly focused on a small group of people, specifically like apartment building/complex/neighbor style shows. Examples of what I've watched include Happiness, Sweet Home, Vincenzo. I really enjoyed the continuous interactions throughout these shows.

Rose Mansion (2022)

Strangers from Hell (2019)

The Killer's Shopping List (2022)

I might be wrong but I think these both shows really fit your description (:

Idk if you watch jdramas but Anata no Ban Desu fits. 

The Village: Achiara's Secret may also kinda fit? Though, it's more of a small village than neighbours.

A beautiful coffee shop owner Zhong Meibao suddenly dies in a condominium at the Horizon Tower. When she died, her face still wore a doll-like makeup, hence the case was referred to as the "Doll Murder Case". This case shocks the whole tower, and after investigation the clues point to three suspects - security guard Xie Baoluo, architect Lin Dasen and property manager Lin Mengyu. All three suspects were enthralled by Zhong Meibao's beauty, and all had an intimate relationship with her. All the clues seem to point to the possibility of a love crime. However in the midst of investigation, new clues begin to emerge, and turns the focus to Zhong Meibao's complicated and painful youth. Her family, consisting of her step-father, mother, younger brother, and foster mother, were implicated into the case. Just who could be the real murderer?

- Eulachacha Waikiki (S1 and S2)

- Fight for my way

Never Twice (2019) - about the residents of a small inn near a large city hotel. They all look out for each other.

Thanks everyone, these suggestions look great. I forgot about Strangers from Hell, loved that one.

Sky Castle - Pretty intense drama revolving around a group of families in a rich neighborhood. I haven't seen the three dramas you mentioned, but I know they are not cutesy dramas, so perhaps you could also enjoy Sky Castle.

Lonely enough to love - On the contrary, this one is a cute romance drama, nothing extraordinary but it fits the concept of apartment building setting.

When the Weather Is Fine - Another romance drama, it has some focus on village life and the bond of some of the villagers. 

The Penthouse - This one I haven't watched but I know it's drama galore, over the top plot and antics of some rich people that live in a high end building.
