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.
