They removed it, I'm not sure why but you can read it https://mangabuddy.com/niichan here.
Also, can you tell where'd you get the audio drama?
That’s so dumb that they removed it (if based on people reporting it). Not everything is romanticized, that was such a brilliant work about showcasing that type of abuse.
i wonder why it got removed but oh well
but i think the latest download link is down so heres the folder
https://drive.google.com/drive/folders/1YTymFPhhwqJv2rRBPuOC-uGv8IlTP9Ds
if thats the reason, i agree thats dumb. harada's works are one of the many that shows how the abuse should be taken seriously and they also dont it use that messed up plot as one-thing only
oh i tried to share the site where you can download the audio drama but i guess it got deleted lmao
anyways you can find it on yaoiotaku ///com
i was planning to reread niichan by harada while listening to its audio drama but found out its currently unavailable?? where did it go
