Sonomama de
Seinen wa ai wo kou
Soredemo, Yasashii koi wo suru
Before daylight love
I know there’s more because friends/coworkers to lovers is such a common theme but I picked a couple that are among some of my favorites and have slightly longer relationships preceding the development of a romantic one. Also the last two are spin offs of other stories but you don’t really need to read the originals to get the gist of things.

Here some of my personal tagged mangas
