OH I DO UNDERSTAND!!!
When reading No. 6 it's like my feels take a mad roller coaster ride in a washing machine on max tumble ε=ε=(ノ≧∇≦)ノ
Never, in all my manga reading experience, have i encountered a manga that can make me feel so elated and devastated, as No. 6 (not to mention fangirling hard enough to fall outa my chair ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄ )
I KNOW WHAT YOU MEAN the only reason it's not my fav yaoi is because the actual plot (other than the romance )isn't as amazing as a lot of other yaoi/shounen ! However in my reading experience, nezushi remains the BEST PAIRING EVER. Like their story and how they met how they feel about each other HOW SHION SAVED NEZUMI and how nezumi changed so much thanks to shion and how they are so drawn to each other and the way they look at each other and how nezumi was baffled by shion's straightforwardness and how they both save each other and .. I'm gonna stop before I end up going overboard but seriously Nezushi gives me so much feels that I get soo excited just from talking about them

I know this is a tough one as there so many good yaoi out there but there must be this one special yaoi that you slightly like better than the others
For me it's definitely kyuuso wa cheese no yume o miru ٩(๑❛ᴗ❛๑)۶
What's yours?
