A few ones green flag ones I think you should check out:
-Melting Point (chasing and yearning)
-Daytime Star (more yearning than chasing)
-While you weren’t watching [SECOND COUPLE] (chasing and yearning)
-Define the Relationship (chasing and yearning from what I remember)
-Heat and Run (more yearning than chasing)
-INSECRET [SECOND COUPLE] (chasing and yearning)
Though not all of them have a lot of chasing, they’re 10/10 yearning stories worth reading.
Hope I helped a bit ;))

can you recommend straight or bl manhwas that have this kind of plot, thank u in advanceヾ(☆▽☆)
