i dont have fujoshi/fudanshi friends but i think Ten Count and the Kuroneko titles are the "must reads"
It's literally just fap material. Most of the writing is shit honestly but I do really enjoy http://www.mangago.zone/read-manga/shimanami_tasogare/ and I think that it is a must read. Because it isn't yaoi. It's a gay romance written by a queer mangaka that does an incredible job at highlighting what it means to be queer without the fetishism of yaoi distorting it.
Also can we agree that the 2nd male lead is way more wholesome. Like I’m so sorry he’s heartbroken
