What anime is this? And where can I read the first part? Plsss help me.

I believe the first part is on nhentai, and probably myreadingmanga idk

nvm someone had a link in the comments https://yaoimangaonline.com/sensei-wa-nekketsu-ga-areba-juubunda-by-fuerzabruta-zawarc-eng/

Thanks... can I also ask what anime is it from? This is a doujinshi right?

I think it's a doujinshi because it was independently published (maybe? idk lol) but they don't seem to come from an anime

Oh ok... thanks then
