welp...that is way too vague. It could be any series Backlight is the one coming to mind right now tho'. In ch 59 there's a panel that seems to fit your description. But idk
If you clicked on the post, you can go through your search hsitory to find it? There's a lot of blond/black haired couples... Was there anything specific about the artstyle?
I only know a few myself, but I'd check out:
Backlight
Guiding hazard
Love me, revive me
The Pizza Delivery Man and The Gold Palace
Just in case it's one of those! Can't guarantee it, but those are the ones I know.
if you remember anything or find the link, lemme know and I'll keep hunting!
