Probably the Inma Kyoiku (Inma Education) series, especially Sasai's route, I love Keisuke Aikawas voice so much but every volume in the series is so good, and its cool and how the characters stories are linked!! and the art is also some of the best I've ever seen
Ahjahha, maybe i misunderstood the question. I'll give an update, my current top drama doujin is トカゲの初恋.
I feel like i wont be able to find another drama doujin that feels like this again. The way it portrays about the angst and sadness of both characters, how the writer narrates it, plus 主水Ash without his dialect .
Drama doujin that i can listen it again and again.
