I need a manga where the uke is masochistic, the seme doesn't necessarily have to be a sadist but he can be indifferent or a tsundere or whatever. But I can't seem to find any manga where the uke is a major masochist except for Shell. I forgot the name of that manhwa...
Plz help

I can't believe you did not heard of Saezuru tori wa habatakanai - The most beautiful, most emotional uke and stoic, loving seme. I definitely recommend it. 😁

uh im a bit late to this but...
Shell is from Blood Bank
and a manga with a dormant M uke that I know: Chou To Hana No Kankeisei by Akabeko

The uke in Kaori no Keisho by Nakamura Asumiko is definitely super masochistic.
