Indie titles are rare. I haven't seen Gelboys
I would definitely call "Gelboys" indie (in the best sense of the word).
"Secrets Happened on the Litchi Island" (which I don't see on Iota's watched list) is *the* low-budget indie masterpiece of 2025. Highly recommended.
"Eighth Sense" (@Iota, not on your watched list) feels very indie and is one of my all-time favourite KBLs.
A lot of JBLs have indie vibes, although I often find it hard to distinguish between "indie vibes" and "JBL vibes".

Benizakura:
Moonlight chicken
I'm not sure I'd dare to say that anything from GMMTV can have "indie vibes", but "Moonlight Chicken" is one of my all-time faves. Highly recommended.

Benizakura:
Moonlight Chicken - realistic imperfect relationships (mild)
"Moonlight Chicken", "See Your Love" and "I Hear The Sunspot" can also be called unconventional relationships because each involves a deaf protagonist. All three are excellent (and @Iota, I don't see any of these on your completed list).
