Manhwa recommendation

for such you can try looking it up at mangaupdates as it contains most of artists/authors/writers/series info + works

https://www.mangaupdates.com/author/h0z2g17/brothers-without-a-tomorrow
here a link for your questioned author.

I don't really know much but here are some in the list that I know

1. Smyrna and Capri

2. Open abroad

3. Foul start

4. Dear 00

5. Blossom of the white night

Etc

There are some with similar art style or they may be from bwat idk

6. Tale of the Yellow dragon

7. Bloodlink

Some of the names may differ from the original names

Nice to see you (I liked this manhwa try this)✌🏻
