Kure-nai - Vol. 1 Ch. 1 - Kurenai Shinkurou

[MangaDex]

 

[DarklordVor]

Surprisingly huge difference from the anime. Murasaki being with Shinkurou during his "job" is very wildly different from how she's supposed to be spending time with his neighbors and protected from her family.

Also Murasaki is much more forthcoming with her crush on him, while in the anime she gave him a kiss and left it at that.
