Need Manga Recommendation (Mystery, Drama, Psychological, and No Romance)

I recently read "The Ichinose Family's Deadly Sins" and ISTG, I can't find any other mangas anymore:(.

Pls recommend me somthing like that (life changing stories). Manga can contain little romance but make sure the romance is not related to MC.

Hoping I get suggestions😔 pls i feel so empty (lol)
