u came to the right place brother
some of my favorites are petshop of horrors by matsuri akino, *catch these hands! by murata, yona of the dawn by mizuho kusanagi, run away with me, girl by battan (warning for domestic abuse iirc?), and in clothes called fat by moyoco anno (talked abt this one before, major fatphobia/eating disorder/etc warning)
i've heard good things about 7seeds by yumi tamura, nodame cantabile by tomoko ninomiya, and life lessons with uramichi oniisan by gaku kaze,and nana by ai yazawa!
