I'm ashamed to say I've avoided reading this because it's omegaverse despite seeing this multiple times at search results and recommendations. This is one of the best manga I've ever read, and is now one of my favorite. Heck, I think it even entered my top 5 or top 3 favorite manga.
I love everything about this manga- from the art to dialogues, and characters and their development. This made me cry, and made my heart ache. I'm not really one to reread manga, but I'm sure I'll come back to this someday.
If I didn't read the comments, I wouldn't realize that there were actually two different story in this. Wtf, they looked so similar I couldn't distinguished. I was like, "what the fuck is happening? The student's heart will be really broken, like wtf is he doing?" And what more, two stories in one, says it's completed but im freaking left here hanging, especially the first couple...is that it??
I've read three or four times, once here and the rest in MRM. Dang, I'm sooo. Wish there were more of Yuki-chan. Lol.
